The control unit 180 may control the driving or operation of the mobile terminal 100 or may perform data processing, function or operation related to the application program installed in the mobile terminal 100 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

Also, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

In this case, a rear cover 103 for covering the mounted electronic components can be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is separated from the rear case 102, the electronic parts mounted on the rear case 102 are exposed to the outside.

As shown, when the rear cover 103 is coupled to the rear case 102, a side portion of the rear case 102 can be exposed. In some cases, the rear case 102 may be completely covered by the rear cover 103 during the engagement. Meanwhile, the rear cover 103 may be provided with an opening for exposing the camera 121b and the sound output unit 152b to the outside.

These cases 101, 102, and 103 may be formed by injection molding of synthetic resin or may be formed of metal such as stainless steel (STS), aluminum (Al), titanium (Ti), or the like.

The mobile terminal 100 may be configured such that one case provides the internal space, unlike the above example in which a plurality of cases provide an internal space for accommodating various electronic components. In this case, a universal mobile terminal 100 in which a synthetic resin or metal is connected from the side to the rear side can be realized.

Meanwhile, the mobile terminal 100 may include a waterproof unit (not shown) for preventing water from penetrating into the terminal body. For example, the waterproof portion is provided between the window 151a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, And a waterproof member for sealing the inside space of the oven.

For example, the first operation unit 123a may not be provided on the front surface of the terminal body, and the second sound output unit 152b may be provided on the side surface of the terminal body rather than the rear surface of the terminal body.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

The display unit 151 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, a 3D display, and an e-ink display.

In addition, the display unit 151 may exist in two or more depending on the embodiment of the mobile terminal 100. In this case, the mobile terminal 100 may be provided with a plurality of display portions spaced apart from each other or disposed integrally with one another, or may be disposed on different surfaces, respectively.

The display unit 151 may include a touch sensor that senses a touch with respect to the display unit 151 so that a control command can be received by a touch method. When a touch is made to the display unit 151, the touch sensor senses the touch, and the control unit 180 generates a control command corresponding to the touch based on the touch. The content input by the touch method may be a letter or a number, an instruction in various modes, a menu item which can be designated, and the like.

The touch sensor may be a film having a touch pattern and disposed between the window 151a and a display (not shown) on the rear surface of the window 151a, or may be a metal wire . Alternatively, the touch sensor may be formed integrally with the display. For example, the touch sensor may be disposed on a substrate of the display or inside the display.

In this way, the display unit 151 can form a touch screen together with the touch sensor. In this case, the touch screen can function as a user input unit 123 (see FIG. 1A). In some cases, the touch screen may replace at least some functions of the first operation unit 123a.

The first sound output unit 152a may be implemented as a receiver for transmitting a call sound to a user's ear and the second sound output unit 152b may be implemented as a loud speaker for outputting various alarm sounds or multimedia playback sounds. ). ≪ / RTI >

The window 151a of the display unit 151 may be provided with an acoustic hole for emitting the sound generated from the first acoustic output unit 152a. However, the present invention is not limited to this, and the sound may be configured to be emitted along an assembly gap (for example, a gap between the window 151a and the front case 101) between the structures. In this case, the appearance of the mobile terminal 100 can be made more simple because the hole formed independently for the apparent acoustic output is hidden or hidden.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

1D is a conceptual diagram illustrating a mobile terminal to which a gas sensor unit is mounted according to another embodiment of the present invention.

Referring to FIG. 1D, the mobile terminal 100 includes a terminal body and a sub-body 210 detachably mounted on one end of the terminal body. Various electronic components including the display unit 151 are disposed in the terminal body. Also, an inner space in which a power supply unit 190 for supplying power is disposed is formed in the terminal body.

The power supply unit 190 is fixed to the sub-body 210 to be detachably attached thereto. The sub-body 210 is fixed to the terminal body to cover the inner space. The sub body 210 includes a second body 212 constituting an outer appearance when coupled with the terminal body and a power supply 190 protruded from the second body 212 and fixed to the inner side of the terminal body 210, And a first body 211 disposed in the space.

The sub-body 210 may be mounted with the first sensor module 301. The first sensor module 301 may be a sensor for measuring the concentration of harmful gas that may affect the human body. For example, the first sensor module 301 may correspond to a sensor for measuring the concentration of volatile organic compounds (TVOC) and / or the concentration of carbon dioxide (CO2) in the air. The sub-body 210 may include an internal space into which the first sensor module 301, which is a module, may be mounted.

The mobile terminal 100 includes the terminal body and the sub body 210. The sub body 210 includes a function body 213 having an electronic component for performing a specific function, And a first body 211 protruded from the first body 213 and having the power supply unit 190 fixed thereto. The functional body 213 and the second body 212 may have different shapes and sizes.

The functional body 213 may also have an internal space in which a second sensor module 302 for sensing the concentration of volatile organic compounds (TVOC) and / or a third sensor module 303 for sensing the concentration of alcohol have.

The first to third sensor modules 300a, 300b, and 300c may be detachable from the second body 212 and the functional body 213, or may be integrally formed. When the first to third sensor modules 300a, 300b and 300c are formed integrally with the second body 212 and the functional body 213, the sub-body 210 is separated from the terminal body The sub-body 210 equipped with the sensor module for sensing gas of a desired type can be mounted on the terminal body.

When the sensor module is detached from the second body 212 and the functional body 213, the user can replace the sensor module that senses a gas of a desired type. In the meantime, the functional body 213 may be fixed with different sensor modules for detecting different types of gas.

Different sensor modules that detect different types of gas may have sensors of different shapes and shapes.

Alternatively, as shown in the figure, the sensor module may be disposed in the internal space of the terminal body. For example, the sensor module may be attached to the inner space of the terminal body 100 exposed after the power supply unit 190 is detached from the terminal main body.

According to the present embodiment, the sensor module that detects different types of gas can be replaced by using the detachable sub-body formed so that the inner space of the mobile terminal body is exposed. Accordingly, the user can acquire desired information by purchasing a necessary sensor module separately.

FIGS. 2A to 2D are conceptual diagrams illustrating an internal structure of a mobile terminal including a sensor module disposed in one area of the mobile terminal of FIG. 1B.

FIG. 2A is a conceptual diagram for explaining an internal structure of a mobile terminal in which a sensor module is disposed in an area adjacent to the rear cover 103. FIG. The mobile terminal 100 includes a receiving area 300 'in which the gas sensor module is mounted inside the inner frame 104 coupled with the rear cover 103 and the rear cover 103.

The rear cover 103, which is an outer appearance of the mobile terminal 100, may be detachable from the inner frame 104. The rear cover 103 and the inner frame 104 each include an air hole 105 including first and second holes 105a and 105b communicating with the receiving area 300 '. Outside air can reach the receiving area 300 'through the second hole 105b by the first hole 105a formed in the rear cover 103. [

FIG. 2B illustrates a first gas sensor module 300 mounted in the receiving area formed by the rear cover 103 and the inner frame 104. FIG.

When the rear cover 103 and the inner frame 104 are separated from each other, the gas sensor module 300 can be exposed to the outside and replaced with a gas sensor module including other types of gas sensors.

The first gas sensor module 300 includes a gas sensor 301, a storage cap 303 for storing the gas sensor 301, a conductive member 306, and a flexible circuit board 181a. The gas sensor 301 is housed in an inner space of the storage cap 303. The storage cap 303 includes a gas hole 302 formed to communicate with the first hole 105a of the rear cover 103, .

The shape of the accommodating cap 303 may be substantially the same as the accommodating area formed by the inner frame 104 and the rear cover 103. The storage cap 303 may be made of a rubber material that can be elastically deformed so as to prevent damage by the impact of the gas sensor 301 and to be replaceable in the mobile terminal 100.

The gas sensor module may be disposed adjacent to the rear cover 103 to ensure a maximum distance from other electronic components, thereby dispersing the heat of the mobile terminal 100. Although not shown in the drawing, it is preferable that the gas sensor module is disposed adjacent to a lower end portion and a side surface of the mobile terminal 100, which are less affected by temperature and humidity and less affected by internal heat.

The type of the gas sensor 300 is not limited. For example, gas sensors can detect carcinogens such as benzene, toluene, and formaldehyde that cause sick house syndrome, detect harmful gases such as ammonia and methane to detect food spoilage, detect poison gas in public places, It is possible to detect harmful gas. The gas sensor can detect carbon monoxide (CO), carbon dioxide (CO 2), ozone, nitrogen dioxide (NO 2), and the like, to check the air cleanliness outside the room, or to sense temperature and humidity. In addition, the gas sensor can sense gas emitted from a human body. For example, the gas senses can detect illness by breathing mouth odor and inflammation in the body, or can measure drinking. In addition, the gas sensor can sense a specific type of gas to discriminate wine, to determine the sugar content of fruit, and to detect pesticides.

2C is a conceptual diagram for explaining a gas sensor module including a plurality of gas sensors. The gas sensor module 300 includes a storage cap 303, a gas hole 302 formed in the storage cap 303, first and second gas sensors 301a and 301b seated in the storage cap 303, .

The first and second gas sensors 301a and 301b may be configured to detect the same kind of gas. Power may be applied to the first gas sensor 301a to detect the gas, and when the life of the first gas sensor 301a is reached, power may be supplied to the second gas sensor 301b to drive the second gas sensor 301b.

The first and second gas sensors 301a and 301b may be sensors that detect different types of gases, and may have different sizes and shapes. The kind of the gas sensor according to the present invention is not limited. For example, gas sensors can detect carcinogens such as benzene, toluene, and formaldehyde that cause sick house syndrome, detect harmful gases such as ammonia and methane to detect food spoilage, detect poison gas in public places, It is possible to detect harmful gas. The gas sensor can detect carbon monoxide (CO), carbon dioxide (CO 2), ozone, nitrogen dioxide (NO 2), and the like, to check the air cleanliness outside the room, or to sense temperature and humidity. In addition, the gas sensor can sense gas emitted from a human body. For example, the gas senses can detect illness by breathing mouth odor and inflammation in the body, or can measure drinking. In addition, the gas sensor can sense a specific type of gas to discriminate wine, to determine the sugar content of fruit, and to detect pesticides.

3A and 3B are conceptual diagrams for explaining a control method of driving a heater of a gas sensor according to an embodiment of the present invention.

The gas sensor included in the mobile terminal 100 according to the present invention may be implemented as a semiconductor gas sensor. The semiconductor gas sensor applies a voltage for heating the heater, and senses the gas using a change in electrical resistance that occurs when the gas contacts the surface of the ceramic semiconductor.

The controller 180 controls the heater to be turned on by a predetermined period without continuously maintaining the heater by turning on the heater. That is, the temperature of the heater forms a pulse and maintains the temperature for sensing the gas. Accordingly, the power consumption for driving the heater can be minimized.

Referring to FIG. 3B, the controller 180 controls the heater to be continuously turned on while the mobile terminal 100 is not in use or consumes a minimum amount of electric power. If the power consumption of the mobile terminal 100 is equal to or greater than a preset reference value, the controller 180 controls the heater to be turned on based on a predetermined period of time .

The controller 180 controls ON / OFF of the heater to be heated to a specific period. The baking function corresponds to a burn-in step in which the heater is driven for a specific time (about 24 hours to about 48 hours) in the initial use to ensure that the performance of the detection sensor is stable during use. When the baking function is executed, the gas particles attached to the sensing material of the sensing sensor are desorbed.

For example, when the power supply unit 190 of the mobile terminal 100 is in a charged state, the control unit 180 displays a confirmation window for confirming the progress of the correction of the gas sensor 300 The control unit controls the display unit 151 so as to output the image data.

The charging terminal may be connected to the interface unit 160 for charging the power supply unit 190 or the confirmation window 510 may be output when the charging unit is switched to the wireless charging state. When a control command for correcting the gas sensor is applied by the confirmation window 510, the controller 180 turns on the heater to perform the baking function, Detach gas particles attached to the sensing material.

While the burn-in function is being performed, the display unit 151 may correct the detection result information and output the correction progress screen 520. The correction progress screen 520 includes a status bar indicating that the burn-in process or the sensed information is being corrected, and the data sensed by the gas sensor module 300 (temperature, humidity, Concentration of carbon dioxide, etc.) and data (e.g., pressure, altitude, location, time, date, etc.) from other sensing sensors.

On the other hand, the controller 180 can perform the baking function in a relatively short time when the mobile terminal 100 is used. For example, the control unit 180 may sense the user's browse time or perform the baking function at a time when the mobile terminal 100 moves less.

Accordingly, it is possible to improve the quality of the gas sensor by efficiently using the power of the mobile terminal 100 by executing the baking function at a time when power consumption is low.

4A and 4B are conceptual diagrams for explaining a control method of sensing gas contained in breathing according to an embodiment of the present invention.

Referring to FIG. 4A, the controller 180 may control the gas sensor module 300 to sense gas while the call function is being executed. When the call function is executed, the display unit 151 outputs the call screen 501. When the gas sensor module 300 is activated, the first sensing image 501, which indicates that the call screen 501 is performing the sensing function, (511). When the gas sensor module 300 includes a gas sensor that detects various kinds of gas, the control unit controls the gas sensor module 300 to detect only the gas corresponding to the call function.

The control unit 180 controls the sensing sensor module 300 based on execution of the call function without a user's specific control command. The control unit 180 may control the output unit 150 of the mobile terminal 100 to output audible data and / or vibration to the sensory sensor module 300 when the sensory sensor module 300 is activated.

The control unit 180 may activate the gas sensor module 300 when the user's face or the like is adjacent to the mobile terminal 100 during the execution of the call function or the call function. Alternatively, the controller 180 may activate the gas sensor module 300 only when performing wireless communication with a specific external device. While the call function is being performed, the gas sensor module 300 senses gases related to human diseases among various kinds of gases. For example, the gas associated with the disease may be VOC gas such as acetone, toluene, nitrogen monoxide, ammonia. Such gases may correspond to biomarkers (biomarkers) of diabetes, lung cancer, asthma, and kidney disease, respectively.

The control unit 180 controls the display unit 151 to display the first result image 521 when the gas sensing module 300 completes the gas sensing from the user's breathing. The first result image 521 may be displayed on the display unit 151 when the call function is terminated. The first result image 521 may be output together with the end screen of the call function, but is not limited thereto. For example, the first result image 521 may be output in the form of a popup window or an event notification form.

The first result image 521 includes a graphic image (YES / ON) for receiving touch information to apply a control command for confirming information and sensing that a specific gas has been detected.

The control unit 180 controls the display unit 151 to output the first result screen 531 based on the touch input applied to the first result image 521. [ The first result screen 531 may include information on the concentration of the specific gas detected by the gas sensor module 300 and a result of analyzing the detection information of the gas. The result of analyzing the detection information may include disease information related to the user's health and guide information for improving the disease information.

When the information is derived by the gas sensor module 300, the controller 180 compares the information with a specific reference value. If the information is out of the reference range or is compared with information measured in the past, The display unit 151 is controlled to output the first resultant image 521 only.

According to the present embodiment, when a call function is executed without a user's control command, a specific kind of gas can be detected from the user's breath. Accordingly, the user consciously inspects the gas contained in the respiration to detect the gas contained in the respiration during use of the mobile terminal 100 without measuring the health state. Therefore, the user can receive health information through breathing even if he / she is not conscious.

4B and 4C, the display unit 151 outputs a second result screen 532 based on the sensed information. The second result screen 532 does not show the measured gas value but includes guide information for improving the user's health based on the measured gas detection information.

Also, the controller 180 may control the display unit 151 to output the third result screen 533 according to the health state according to the gas level. The third result screen 533 may include warning information indicating the necessity of treatment and treatment when the detection information of the specific gas is out of the reference range indicating the scale of health. For example, the third result screen 533 may include data on the risk of disease, hospital information, and the like. The reference range indicating the measure of health may be stored in the memory 170 or received from a specific server.

Referring to FIG. 4C, the controller 180 controls the display unit 151 to output a fourth result screen 534 including information on a behavioral alert, based on the downtown information. For example, the fourth result screen 534 may include warning information for preventing drunken driving according to the alcohol level. The controller 180 controls the display unit 151 to display the fourth result screen 534 at a predetermined period of time.

That is, the controller 180 displays different kinds of result information based on the type and numerical value of the detected gas, so that the user can be provided with the guide information for health as well as the numerical values of the gas included in the respiration .

5A to 5D are conceptual diagrams illustrating a control method of sensing gas based on position information according to another embodiment.

Referring to FIG. 5A, the location information unit 115 collects location information (S11). The control unit 180 receives the position information once when a specific function (e.g., GPS function, navigation function, route finding function) is executed or once at a specific period.

If the position information is collected or a predetermined control command is applied, the controller 180 detects the air condition and analyzes it (S12). Referring to FIG. 5B, the controller 180 may activate the position information collecting function and the gas sensing function on the status display screen 610. The status display screen 610 includes a first setting icon 611 for receiving a touch input and a second setting icon 612 for receiving a touch input for activating the gas sensing function to activate the position information collecting function, . In addition, the status display screen 610 may include a second resultant image 522 representing the sensed information collected based on the gas sensing function. The second result image 522 may be displayed on a notification image indicating the occurrence of an event. The second resultant image 522 may represent a result of analyzing the sensed information or may correspond to a graphic image representing the sensed information as a numerical value.

The controller 180 determines whether the amount of change in the air condition is equal to or greater than a reference value (S13). The controller 180 controls the memory 170 to store the position information and the air state data together when the change amount of the air state is equal to or greater than the reference value, ).

The controller 180 displays a graphic image indicating the air condition (S15). Referring to FIG. 5B, when the amount of change is equal to or greater than a reference value, an event notification bar including the second result image 522 may be output. The controller 180 may execute a specific application for informing the air condition based on the touch input applied to the event notification bar.

The second resultant image 522 may be an image representing an air pollution level corresponding to the air quality. The image may be of different colors, shapes, etc. based on the level of air confusion.

The position information and the air condition stored together based on the touch input applied on the notification bar including the second result image 522 are displayed on the display unit 151. [ For example, the position information is displayed on the map screen 541, and a third result image 523 indicating the air condition (sensing information) corresponding to each position information is displayed on the map screen 541. That is, the air condition at the corresponding position can be displayed based on the position on the map screen 541 on which the third result image 523 is outputted.

According to this embodiment, while the air condition is detected, the position information is also collected and the air condition corresponding to the position can be detected, so that the user can be provided with the air condition at the corresponding position.

Referring to FIG. 5C, the display unit 151 may display a fourth result image 524 indicating the currently measured air condition (sensing information) on the map screen 541. The fourth result image 524 includes sensed information measured at the current position.

The control unit 180 activates the gas sensor module 300 and the sensing unit based on a specific control command (selection of a menu) while the map screen 541 is output. The sensing unit senses movement, rotation, acceleration, and the like of the mobile terminal 100. The control unit 180 may display the movement of the mobile terminal 100 sensed by the sensing unit in the fourth result image 524. [

The fourth result image 524 may include a setting for setting a function related to the gas sensing function. For example, the setting may include adding a picture, adding a moving picture, setting a sharing, setting a notification period (setting a notification period), detecting a gas period, and the like. When the photograph addition function is set, the control unit 180 can activate the camera 121 together to photograph the gas sensor module 300 when the gas sensor module 300 is activated.

Meanwhile, the controller 180 controls the gas sensor module 300 to suspend the gas sensing function when the sensing unit detects movement over a predetermined reference level. The control unit 180 controls the gas sensor module 300 to detect gas when a motion of a certain level is detected by the sensing unit. The display unit 151 displays the second sensed image 512 when the gas sensor module 300 is activated. For example, the specific criterion may correspond to a case in which no motion is detected for a specific time (about 15 minutes).

The second sensing image 512 may be displayed in a pop-up window format on the home screen page 500 or the second sensing image 512 may be displayed together with the map screen 541.

The controller 180 activates the camera 121 according to the activation of the gas sensor module 300 based on the setting of the user. The control unit 180 controls the memory 170 to store the sensing information measured by the gas sensor module 300 together with the photographs obtained by the activated camera 121. [

The display unit 151 displays the fifth result image 525 by the gas sensor module 300 on the captured image 542 obtained by the camera 121. [ Although not shown specifically in the drawing, the controller 180 may be configured to determine the details of the sensed information, the position information, and the sensed image 542 based on the touch input applied on the fifth resultant image 525 The display unit 151 can be controlled to display specific information.

Alternatively, when the touch input for selecting a specific position on the map screen 541 is applied, the controller 180 controls the display unit 542 to output a fourth result image 542 including sensing information stored together with the position information, (151).

According to the present embodiment, since the gas sensor module can be activated when the motion state of the mobile terminal 100 is stable, the air condition around the mobile terminal 100 can be detected more accurately. In addition, additional information can be stored together with measured sensing information by performing additional functions when measuring the air condition.

Referring to FIG. 5D, the display unit 151 may display a third setting icon 613 for receiving a touch input to display an additional air condition on the map screen 541. The map screen 541 may include location information that is close to the current location or may include information about the location of the mobile terminal 100.

The control unit 180 displays the position information indicating the movement of the mobile terminal 100 and the sensing information indicating the sensed air condition based on the touch input applied to the third setting icon 613. [ And controls the display unit 151. For example, the location information may indicate a change in the location of the mobile terminal 100 during the current day.

The display unit 151 displays a route screen 543 indicating location information including the movement path of the mobile terminal 100 and displays a fourth result image 526 indicating the detection information on the route screen 543 ). The fourth result image 526 is displayed in one area on the path screen 543 corresponding to the position where the sensing information is collected by the gas sensor module 300.

Accordingly, the user can be provided with the map of the air condition at the corresponding position included in the route together with the route moved during a specific period (day).

6A to 6C are conceptual diagrams for explaining a control method of detecting a gas set based on the position of the mobile terminal according to another embodiment.

6A and 6B, the controller 180 activates the vehicle mode when the specific condition is satisfied (S21). For example, the control unit 180 wirelessly connects with the vehicle when receiving the vehicle, and receives the wireless signal. The control unit 180 activates the vehicle mode of the mobile terminal 100 when it is wirelessly connected to the vehicle or receives a wireless signal. Alternatively, when the moving speed of the mobile terminal 100 is detected by the sensing unit to be greater than a predetermined reference speed, the control unit 180 determines that the vehicle is boarded and activates the vehicle mode. However, the present invention is not limited thereto, and the vehicle mode can be activated when a control command for controlling the function of the vehicle is applied by the user.

The control unit 180 determines whether or not a specific time has elapsed since activation in the vehicle mode (S22) and whether the running speed is equal to or higher than a specific reference speed (S23) in the vehicle mode.

The control unit 180 senses a gas corresponding to the vehicle mode when a predetermined time or more has elapsed and the traveling speed is determined to be equal to or higher than a specific reference speed. The gas corresponding to the vehicle mode may be set by the user or determined by the driving state information of the vehicle received from the vehicle. For example, the gas corresponding to the vehicle mode may correspond to carbon dioxide in the vehicle, but is not limited thereto. When the window of the vehicle is open, gas for measuring the degree of soot flowing from the outside can be sensed.

The control unit 180 measures the concentration of carbon dioxide (S24), and determines whether the concentration of the detected carbon dioxide is equal to or higher than the reference concentration (S25)

When the detected concentration of carbon dioxide is less than the reference concentration, the controller 180 detects and compares the activation elapsed time of the vehicle mode and the running speed of the vehicle. The control unit 180 controls the display unit 151 to output a result screen or a warning image including sensing information on the concentration of carbon dioxide when the concentration of the carbon dioxide is equal to or higher than the reference concentration (S26).

Referring back to FIG. 6B, the display unit 151 outputs a fifth result screen 535 based on the concentration of the detected gas. The fifth result screen 535 may include a type of gas detected, a gas concentration, a reference concentration, and an indicator (In car) indicating a vehicle mode.

The display unit 151 may display a first result image 535a including guide information for changing the concentration of the detected gas. For example, the guide information may include guide information for guiding the opening and closing of the window of the vehicle, recommending the pause and rest of the operation, and the first result image 535a may be text and / or image .

The display unit 151 displays a second result image 535b including guide information for varying the concentration of the gas, and the second result image 535b displays a graphic for controlling the driving state of the vehicle Image. The control unit 180 may transmit a control signal to the vehicle based on a touch input to the graphic image. For example, the controller 180 may control the wireless communication unit 110 to transmit a control signal for opening a window to the vehicle based on a touch input applied to the second result image 535b. Accordingly, the user can change the driving state of the vehicle in order to change the concentration of the gas using the mobile terminal 100.

According to the present embodiment, the type of the gas and the concentration of the gas harmful to the driver are sensed in the space where the user is located while the vehicle is operating, so that the user can check the information of the gas detected during the operation and take measures . Therefore, it is possible to prevent the intake of harmful gas during operation or to maintain a comfortable state through ventilation.

Referring to FIG. 6C, the display unit 151 outputs the fifth result screen 535 including gas sensing information. The control unit 180 may transmit the radio signal corresponding to the fifth result screen 535 to the vehicle 10 while outputting the fifth result screen 535. [ For example, when the external display device 11 is mounted in the vehicle 10, the external display device 11 receiving the radio signal outputs a warning message or outputs audible data 535c do.

Alternatively, the control unit 180 controls the sound output unit 122 to output the auditory data 535d while outputting the fifth result screen 535. The auditory data 535d may be a voice representing guide information.

According to the present embodiment, the user can be provided with sensing information when a gas harmful to the body is sensed or the concentration of the gas is harmful during operation without any separate control command. Since the sensed information is displayed by the auditory data or an external device mounted on the vehicle, the user can recognize the sensed information and take measures so that it can operate in a stable condition.

7A to 7D are conceptual diagrams for explaining a control method of detecting different gases according to a driving state of a vehicle according to another embodiment.

7A to 7C, the controller 180 controls the wireless communication unit 110 to receive driving state information D1 and D2 of the vehicle from the vehicle (S31). The wireless communication unit 110 can receive the driving state information of the vehicle once at a specific period while being in the vehicle.

Upon receiving the driving state information (D1, D2) of the vehicle 10, the controller 180 selects the type of gas to be detected based on the driving state information (S32). Referring to FIGS. 7B and 7C, the first driving state information D1 includes information that the window of the vehicle is open. The controller 180 controls the gas sensor module 300 to sense the gas contained in the soot based on the first driving state information D1. In this case, the display unit 151 displays a third sensed image 513 including a message of confirming the soot. The third sensed image 513 may include a control image to limit the driving of the gas sensor module 300.

On the other hand, the second driving state information D2 may include information that the window of the vehicle is closed. Based on the second driving state information D2, the controller 180 controls the gas sensor module 300 to detect carbon dioxide in the vehicle. The display unit 151 outputs a third sensing image 513 indicating the detection of the carbon dioxide.

The display unit 151 displays fourth and fifth sensing images 514 and 515 indicating the degree of measurement of each gas while the gas selected by the gas sensor module 300 is sensed at step S33 can do. The fourth and fifth sensing images 514 and 515 may include a measurement state of the gas sensor module 300, a kind of gas to be measured, a reference value of a predetermined normal range, and the like.

When the detection of the concentration of gas and gas by the gas sensor module 300 is completed, the controller 180 displays the result screen information on the basis of the sensed gas detection information and the driving status information (S34). For example, when the concentration of the soot is equal to or greater than the reference value in a state where the window is opened by the first driving state information (D1), the display unit 151 displays a sixth result screen including a warning message 536a.

Meanwhile, the display unit 151 outputs a sixth result screen 536b including a warning message to open the window and to vent when the concentration of the carbon dioxide is equal to or higher than the reference value in a state where the window is closed.

Accordingly, even if the user does not set the kind of gas to be measured according to the state of the vehicle, the mobile terminal can selectively detect the gas according to the type of the received vehicle.

Referring to FIG. 7D, the third driving state information D3 may include position information of the vehicle. The control unit 180 controls the gas sensor module 300 to sense gas corresponding to the specific position when the vehicle 10 is traveling at a specific position based on the third driving state information D3. can do.

For example, when it is determined that the vehicle 10 is passing through the tunnel, the controller 180 controls the gas sensor module (not shown) to detect a gas of a selected type to grasp the internal air state and the air state introduced from outside. 300). The display unit 151 may display a sixth sensing image 516 indicating that the gas sensor module 300 is being driven. The sixth sensing image 516 may include information about the current position of the vehicle 10 included in the third driving state information D3. Accordingly, the user can recognize the reason why the gas sensor module 300 is activated and grasps the air condition.

The controller 180 displays the fifth result screen information 536c based on the gas sensing information and the third driving status information D3. The control unit 180 may control the display unit 151 to output the fifth result screen information 536c at a time when the third driving state information D3 is out of the region having a lot of smoke. The control unit 180 controls the wireless communication unit (not shown) to receive the third driving status information D3 (all or a part) continuously for a predetermined time after the sensing information is formed by the gas sensor module 300 110).

For example, when the controller 10 determines that the vehicle 10 is out of the tunnel based on the third driving state information D3, the controller 180 outputs the sixth result screen information 536c, The control unit 151 can be controlled.

8A and 8B are conceptual diagrams for explaining a control method for detecting the type of gas set using the position information of the mobile terminal.

Referring to FIG. 8A, the controller 180 controls the position information unit 115 to acquire position information at a specific period. The controller 180 selects the type of gas to be sensed based on the position information A1 obtained by the position information unit 115. [ For example, when the mobile terminal 100 is located indoors, the controller 180 controls the gas sensor module 300 to detect the concentration of carbon dioxide. The control unit 180 controls the display unit 151 to display a seventh sensed image 517 indicating the concentration of the carbon dioxide.

When the position sensed by the position information unit 115 changes, the controller 180 controls the gas sensor module 300 to detect other gas corresponding to the changed position. For example, when the position information unit 115 acquires position information (A2) for another position by the position information unit 115, the controller 180 controls the gas sensor module 300 to sense the corresponding gas . The display unit 151 includes an eighth sensing image 518 indicating that the new position information A2 is changed to the outside.

In this case, the seventh and eighth sensing images 517 and 518 may include acquired position information and information indicating that the position is changed.

The display unit 151 may display a type of gas being measured on the seventh and eighth sensing images 517 and 518 and may include a control image for selecting the type of the gas.

According to the present embodiment, since the mobile terminal can detect different kinds of gas according to the position of the mobile terminal and can grasp the current air condition, the user does not have to set the kind of gas to be sensed according to the position movement.

FIG. 8B is a conceptual diagram showing a setting screen for setting the sensing function of the gas sensor module 300. FIG.

The setting screen 503 includes a plurality of setting images. The first setting 503a includes information on the most recently measured air condition. The second setting 503b includes a graphic image for setting the temperature of the heater included in the gas sensor module 300. [ The type of gas to be detected is determined based on the temperature of the heater. The second setting 503b may be bar shaped to receive a touch input and deformed, and the type of gas corresponding to the temperature may be displayed along with the bar shape.

The third setting 503c may include an image for receiving a touch input to set an alarm capability based on the air condition of the room being measured. The level of the air condition for outputting the alarm and the on / off of the alarm can be set. Also, the third setting 503c may set the type of gas to output an alarm.

When the detection of the gas is completed by the gas sensor module 300, the display unit 151 outputs a seventh result screen 537. For example, the seventh result screen 537 may include sensing information indicating an air condition, a date and time of sensing gas, and an analysis result (warning).

The control unit 180 controls the display unit 151 to display a first control image 517a corresponding to the additional information received from the server on the seventh result screen 537. [ The control unit 180 may control the wireless communication unit 110 to receive data on the current air condition from a specific server while the gas sensor module 300 detects gas.

The control unit 180 may output the first control image 517a corresponding to the received wireless state data together with the seventh result screen 537 or may output the first control image 517a, The display unit 151 may be controlled to display the first control image 517a when the data and the wireless data received from the server are different.

That is, the seventh result screen 537 is switched to the first server data 571. The first server data 571 may correspond to a web page connected to the server.

Referring to FIG. 9B, the display unit 151 includes the seventh result screen 537 and a second control image 572a including specific air condition data. The control unit 180 compares the wireless data received from the server with the sensing information sensed by the gas sensor module 300. When there is different information, the control unit 180 transmits a second control image including the different information 572a.

Accordingly, the controller 180 displays the second server data 572 based on the touch input applied to the second control image 572a based on the touch input applied to the second control image 572a The display unit 151 can be controlled. The second server data 572 may correspond to a web page of the specific server.

Alternatively, the controller 180 may control the display unit 151 to selectively display the second control image only when the warning data is included according to the server data. It is possible to preferentially display the sensing information or the wireless data based on the setting of the user.

According to the present embodiment, since the user can receive not only the detection information by the gas sensor module 300 mounted on the mobile terminal 100 but also the data received from the server, more precise information can be provided.

10A and 10B are conceptual diagrams for explaining a control method of controlling the gas sensor module based on stored information.

The controller 180 may control the gas sensor module 300 to sense a specific gas selected based on the calendar information. For example, when the calendar information includes outdoor location information, the controller 180 controls the gas sensor module 300 to measure the concentration of fine dust.

The controller 180 controls the gas sensor module 300 based on time information included in the calendar information. The control unit 180 controls the display unit 151 to display a ninth sensed image 519 indicating that the gas sensing is being performed after the notification screen is output or together with the notification screen.
