D203B Dual Elements Passive Infrared PIR Sensor used for Alarm Systems

Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage.

Features:

1. Large detection angle
2. Custom design is available
3. Higher in cost-performance
