Routines, segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, and variables.

Components and the functionality provided within those components may be combined into a smaller number of components or further separated into additional components.

The environmental information collecting unit 110 includes one or more sensors 112 and 114 to provide attribute information about air such as room temperature, indoor humidity, indoor carbon dioxide concentration, or volatile organic compound (VOC) concentration, and the like. Collect. For example, a sensor for detecting a temperature, a sensor for detecting a humidity, a sensor for detecting a carbon dioxide concentration, or a sensor for detecting a VOC may be included. Each of the sensors 112 and 114 transmits the level of the temperature or humidity, CO ₂ or VOC concentration by the magnitude of the voltage. For example, each sensor generates output data in the form of temperature voltage Vt, humidity voltage Vh, CO ₂ voltage Vc or VOC voltage Vv.

In addition, the environmental information collecting unit 110 includes a first connector 116 to be detachable from the main body 120. Various sensors included in the environmental information collecting unit 110 has a lifespan of only one to two years, so the nature of the consumables needs to be replaced periodically. To this end, the environmental information collecting unit 110 is configured to be detachable from the main body 120. The first connector 116 is connected to the first corresponding connector 121 of the main body 120 to transmit a signal from the first sensor 112 to the n-th sensor 114 to the main body 120. In addition, the environmental information collecting unit 110 includes an outer shell for protecting the sensor and the connector, the outer shell may include a windshield (not shown) to allow the indoor air to contact the sensor well.

The main body 120 includes a first corresponding connector 121, an AD converter 122, a voltage control unit 123, a mapping table storage unit 124, a power supply unit 125, and a second corresponding connector 126. .

The first corresponding connector 121 is connected to the first connector 116 of the environmental information collecting unit 110, and receives various sensing information (temperature, humidity, CO ₂ concentration, or VOC concentration received from the environmental information collecting unit 110). ) Is transmitted to the AD converter 122. In this case, the first mating connector 121 may be selectively connected to or disconnected from the first connector 116.

The AD converter 122 converts various sensing information (Vt, Vh, Vc or Vv) in analog form received from the environmental information collecting unit 110 into digital data form. For example, it is converted into 8-bit or 16-bit digital data, and the sensing information can be expressed as Vtd, Vhd, Vcd or Vvd.

The voltage controller 123 receives the sensing information converted into a digital form and controls the voltage to be supplied to the character mood lamp 130 through the power supply unit 125 according to the value stored in the mapping table storage unit 124.

The mapping table storage unit 124 stores a voltage control signal indicating the magnitude of the voltage to be supplied to the character mood lamp 130 according to the sensing information in the digital form. That is, the voltage control signal values corresponding to the various sensing information (Vtd, Vhd, Vcd, Vvd) in digital form are stored. For example, in the case of three voltage control signals corresponding to the output value (R, G, B), a mapping table may be configured by setting a function relationship corresponding to two different sensing information.

2 is a diagram illustrating a mapping table according to an embodiment of the present invention.

As shown in the figure, three voltage control signals are recorded according to two different sensing information values.

First, the sensing information is assumed to have a value of 0 to 255 as 8 bits of digital data. Since CO ₂ and VOC values are independent sensing information, voltage control signal values for a total of 256 * 256 cases are recorded. At this time, the first voltage control signal R for controlling the red color is determined according to the value of CO ₂ . That is, when the concentration of CO ₂ is low and the value is 0, the first voltage control signal R becomes 0 to minimize the red color. In addition, when the concentration of CO ₂ is maximum and the value is 255, the first voltage control signal R becomes 255 to maximize the red color.

In addition, the second voltage control signal B for controlling the blue color is determined according to the value of VOC. That is, when the concentration of the VOC is low and the value is 0, the second voltage control signal B becomes 0 to minimize the blue color. In addition, when the concentration of the VOC is maximum and its value is 255, the second voltage control signal B becomes 255 so that the blue color is maximized.

In addition, the third voltage control signal G for controlling the green color is determined by the exponential function value that changes according to the values of CO ₂ and VOC. The exponential function may be G (CO ₂ , VOC) = 255 * exp (− (CO ₂ + VOC) / 255), as shown.

That is, when the concentrations of VOC and CO ₂ are low and the values are all 0, the third voltage control signal G becomes 255 to maximize green. At this time, since the first voltage control signal R and the second voltage control signal B both become 0, the color output through the LED becomes green.

In addition, when the concentration of VOC and CO ₂ is high and the value is both 255, the third voltage control signal G becomes 255 * exp (-2) so that green is minimized. At this time, since the first voltage control signal R and the second voltage control signal B are both 255, the color output through the LED becomes purple.

As described above, by setting three voltage control signal values differently for two different sensing information, it is possible to visually check the state of each sensing information only by the value output through the tricolor LED. In addition, by storing a plurality of data for each sensing information, the value output through the three-color LED is to be changed continuously. The above example is merely an embodiment, and the type of sensing information may be changed, or the type of voltage control signal according to each sensing information, that is, the type of color may vary.

The power supply unit 125 supplies a voltage to the character mood lamp 130 according to the voltage control signals R, G, and B received from the voltage controller 123.
