Pyroelectric infrared sensor is a sensor that uses the characteristics of spontaneous polarization of materials with temperature change to detect infrared radiation, using dual sensitive element design, internal installation of patch, resistance, capacitor filtering to enhance the ability to interfere with radio frequency, high 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.
