A wired PIR (Passive Infrared) motion sensor is a security device designed to detect motion by sensing changes in infrared radiation, typically emitted by the human body or other warm objects. The sensor consists of a pyroelectric sensor that detects variations in infrared energy, triggering an alert when motion is detected. The "wired" aspect of this sensor means it is physically connected to a security system via electrical wires, providing a stable and reliable power source for continuous operation. Wired PIR motion sensors are often used in security systems to monitor entryways, hallways, or other areas, and can trigger alarms, lights, or even notify the user via connected systems when movement is detected. These sensors are highly effective in detecting motion in indoor and outdoor environments and are commonly used in both residential and commercial properties to enhance security. They are known for their energy efficiency, accuracy, and ability to differentiate between human movement and other environmental changes.
