pir  infrared sensor  detects  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 with the EMI components. As a result, the operating
stability of the sensor is greatly improved. Our products can be used world wide for
many applications. Such as in security systems, burglar alarms, visitor
acknowledgement, light switch control and intellectualized toy, etc.
