How Motion Detection Works
-
Passive Infrared (PIR) Sensors
Most common in motion-sensing lights, PIR sensors detect heat changes in infrared wavelengths. Effective up to ~10 meters, often with Fresnel lenses for wide coverage.Wikipedia -
Other Sensors
Motion detection may also use radar, microwave, tomographic, or even Wi-Fi signal variation, depending on the sophistication of the device.Wikipedia+1
