Product Description
All-Purpose Dual Elements Pyroelectric Infrared Radial Sensor
The pyroelectric infrared sensor detects infrared radiation on the basis of the
characteristics that the 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. Our products can be used in many applications. Such as in security systems,
burglar alarms, visitor acknowledgement, light switch control and intellectualized toy,
etc.
