A Motion Sensor (PIR Detector) is an electronic security device that detects human movement by sensing changes in infrared (heat) energy, triggering alarms, lights, or other security systems.
A Passive Infrared (PIR) Motion Sensor is widely used in security and automation systems to detect unauthorized movement within a monitored area. It works by sensing the infrared radiation emitted by people and animals without emitting any energy itself. PIR detectors can be installed on walls or ceilings and are available in wired and wireless models. Advanced versions combine PIR with microwave technology to minimize false alarms caused by environmental factors. These sensors integrate seamlessly with alarm control panels, CCTV systems, smart home platforms, and automatic lighting systems.
