The passive infrared (PIR) motion sensor detects movement of infrared light sources with wavelengths ranging from 7 μm to 14 μm. Since people emit infrared radiation from 8 μm to 14 μm, 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.
