Digital Intelligent PIR Sensor HL312

It is a low-power pyroelectric infrared sensor (PIR) for motion detection. Using the MCU for communication, when the RS412 performs continuous motion sensing, the MCU does not need to be activated, it only activates the external MCU when motion is detected.

The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature.

The product is a type of intelligent PIR sensor which integrates digital circuit and sensitive element in a hermetically sealed package. It interfaces directly with up two conventional PIR sensors via a high impedance different

PIR sensor module developed for human body detection.

This is a type of PIR sensor which integrates AD chip and sensitive element in a hermetically sealed package.The sensitive element transmits the sensed human body movement signal to the AD chip, which outputs 16-bit digital signals through collection, filtering, etc., and realizes related functions through the peripheral circuit MCU.
