Human Pyroelectric Infrared Radial Detector D203B

D203B Dual Element 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.   Applications 1.security systems 2.burglar alarms 3.light switch control  4 intellectualized toy 5.visitor acknowledgement   Standards and specifications
