A PIR (Passive Infrared) motion sensor is a type of sensor that detects changes in infrared radiation within its field of view. It is commonly used in security systems, lighting control, and home automation applications. PIR motion sensors in general operate based on the principle that all objects emit some level of infrared radiation, which increases as their temperature rises. The PIR sensor is designed to detect changes in this infrared radiation caused by the movement of objects within its range. Typically, PIR motion sensors have an adjustable range and sensitivity settings, allowing them to be customized based on the specific requirements of the installation. They are widely used in indoor and outdoor environments and are known for their energy efficiency and reliability.
