The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the self-polarization of pyroelectric material changes with temperature. Dual compensated sensing elements are applied to suppress the interference resulting from temperature variation. As a result, the operating stability of the sensor is greatly improved. It can be widely used in many applications such as in
Intellectualized toy, automatic light switch control, and visitor acknowledgement etc., especially in the field of intellectualized toy applications.
