PIR Sensor Application in Smart Doorbell, Ceiling light and Camera

Pyroelectric Infrared Sensor detects infrared radiation by using the characteristics of spontaneous polarization of materials changing with temperature. It adopts dual-sensitive element design to suppress the interference caused by changes in ambient temperature and improve the working stability of the sensor. This product is widely used, such as smart toys, automatic light switches, induction doors, smart doorbell, ceiling light and camera.
