movement sensor
Detects nearby motion
A movement sensor is a device that detects physical motion in its vicinity, typically triggering a response like turning on lights, sounding an alarm, or opening automatic doors.
Also called a motion sensor or motion detector.
The technology varies—infrared sensors detect body heat, while others use ultrasound or microwave signals to sense movement.
