Information

Infrared sensor (infra-red sensor in English), as the name implies, is an instrument that uses infrared to perform sensing. Its working principle is: infrared is used as a medium to complete the measurement function. Because of its fast response speed, it is now widely used in many fields such as industry and agriculture, national defense, and science and technology.

 

Sensors are classified according to different principles, and infrared sensors are just one of them. Of course, it can also be further classified according to certain conditions. For example, according to the different driving modes of the infrared beam tube, it can be divided into level type and pulse type; according to the different detection principle, it can be divided into photon detector (detection principle based on photoelectric effect) and thermal detector (detection principle based on thermal effect) ); According to the different functions, it can be divided into five categories: radiometer, search and tracking system, thermal imaging system, infrared ranging communication system and hybrid system.

 

Infrared induction welcome board

 

The working principle of the infrared system: target to be measured→atmospheric attenuation→optical receiver→radiation modulator→infrared detector→detector cooler→signal processing system→display device.

 

1. Target to be tested: Set the infrared system according to its infrared radiation characteristics.

 

2. Atmospheric attenuation: When the infrared radiation of the object to be measured passes through the atmosphere, it will be attenuated due to the influence of various substances.

 

3. Optical receiver: used to receive part of the infrared radiation and transmit it to the infrared sensor.

 

4. Radiation modulator: also known as modulation disc or chopper, used to modulate the infrared radiation in a form of transmutation to provide the orientation information of the object to be measured and filter out interference signals.

 

5. Infrared detector: It is the core of the infrared system and is used to detect infrared radiation.

 

6. Detector cooler: used to cool the system to improve work efficiency.

 

7. Signal processing system: amplify and filter the signal to extract the required information and deliver the effective information to the display device.

 

8. Display device: It is the terminal device of the infrared system, used for the display of effective information.

 

The main functions of the infrared induction welcome board developed by Sanjing are: 1. Infrared induction; 2. Touch remote control; 3. Voice prompt (voice can be customized); 4. Alarm function, etc. There are different development solutions for different product usage scenarios. If you have custom requirements, please contact us for customization.
