Passive Infrared (PIR) Detector SE-10

The passive infrared detector (PID) motion sensor SE-10, also called a passive infrared (PIR) sensor, detects movement of infrared light sources at 7 to 14 μm. People emit infrared radiation from 8 to 14 μm, which makes this an excellent sensor for detecting human movement. Two infrared detector “pixels” allow the detector to filter out changes affecting the whole sensing area, like weather or light.
