1, the data collecting IoT device 100 of the present invention is connected to various kinds of sensors 200a, 200b, ..., 200n and collects data. The data collecting IoT device 100 includes RS232, RS485, 12C, SPI, etc. are also connected and data can be transmitted and received.

The sensors 200a, 200b, ..., 200n are designed to measure various physical properties and are developed and used in accordance with the characteristics, and sensors of new functions are being continuously researched and developed. Representative sensors that are currently commercialized include temperature sensors, humidity sensors, ultrasonic sensors, infrared sensors, biosensors, image sensors, and the like. However, the present invention is not limited to the listed sensors, and more various sensors can be used. The characteristics of the sensors listed in the reference will be briefly described as follows.

Temperature sensors are used to automate temperature management by sensing changes in temperature with sensors that respond to changes in temperature. A temperature sensor is a sensor that senses heat and emits an electric signal. It is generally divided into a contact type and a non-contact type. The contact type is a method of measuring the temperature value by directly contacting the object to be measured, and the non-contact type is a method of measuring the heat ray radiated from the object. A temperature sensor is an electronic circuit device that has a characteristic of a low resistance temperature coefficient that decreases its resistance value when the temperature rises. It is often used as a temperature control sensor because its thermal capacity is small and a rapid resistance change occurs even in a minute temperature change.

The humidity sensor is a sensor that measures the amount of water vapor in the air. It is a type of chemical sensor for detecting the humidity in the atmosphere. It is a sensor that detects mainly by color change and ion amount change due to chemical reaction in the air.

Ultrasonic sensor is a sensor that detects the distance or thickness movement by using the characteristics of ultrasonic wave or generating ultrasonic wave. It is used for ultrasonic welding, washing machine, plastic bonding and processing, high pressure and production control, nondestructive inspection, intrusion inspection, It has low sound pressure used for medical diagnosis, delay line, signal processing and so on. It is also used for detection and detection of sound to an ultrasonic sensor used to perceive an object in a robot or a u-sensor and to detect the distance. When a piezoelectric element having a specific crystal structure and a high voltage pulse are applied, vibration occurs due to electrostatic attraction There is an electrostatic effect method. In other words, the ultrasonic sensor is a sensor that detects the sound in the air. It measures the time from the ultrasonic pulse emitted from the ultrasonic sensor to the ultrasonic sensor reflected from the surface of the object to be returned to the ultrasonic sensor. Method.

The acceleration sensor is a sensor that measures the acceleration or impact strength of a moving object. The acceleration sensor senses dynamic forces such as acceleration, vibration, and shock and uses inertial force, electric deformation, and application management of the gyro. Factory automation, mobile phones and robotics. Because of the ability to measure the acceleration or direction of a moving object, the robot is mainly used to recognize its position and motion, and demand for mobile devices is rapidly increasing.

The infrared sensor is a device that detects the physical quantity and stoichiometry such as temperature, pressure, and radiation intensity by using infrared rays and converts it into electricity that can be processed by signal. It detects that the machine emits and blocks infrared rays, It is mainly used for crime prevention and fire detection. A commonly used human body detection sensor uses a pyroelectric infrared sensor that detects the infrared wavelength emitted by the human body. Since the infrared ray is detected by converting the infrared ray into heat, a filter that passes only a specific wavelength band is used.

A biosensor is a device that investigates the properties of a substance using the functions of living things. It is a type of chemical sensor that uses biological elements to obtain information from a measurement object or changes it into a recognizable useful signal such as a color fluorescence electrical signal by a biochemical reaction.

Finally, the image sensor can be roughly divided into an imaging device and a solid image sensor as an electronic device that converts subject information into an electrical image signal.

The types of sensors 200a, 200b, ..., and 200n that are commercially available and commercially available are numerous, and the outputs of the sensors can be largely divided into digital data, analog data, and pre-calibrated digital data.

The data collecting apparatus 100 senses object information, state information, and user activity information sensed individually as IoT devices from the sensors 200a, 200b, ..., 200n through wired / wireless communication, Collected and processed in real time and transmitted to the upper platform of the server (not shown) in real time using the communication network.
