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.
