PIR motion sensor

The PIR (Passive Infrared) Motion Sensor is a reliable and efficient sensor used to detect motion by measuring changes in infrared radiation levels emitted by surrounding objects. It is widely used in security systems, automatic lighting controls, and other applications requiring motion detection. The sensor is designed to detect human movement and can trigger alarms, lights, or other systems in response to detected motion.
