Pyroelectric infrared sensor D203S (4.5mm)


Pyroelectric infrared sensor is a sensor that 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, etc., especially suitable for smart toy applications.
