PIR Motion Sensor

The PIR Motion Sensor is a compact and reliable module designed to detect movement by sensing changes in infrared radiation (heat) emitted by people and other warm objects. It is an excellent choice for security systems, automatic lighting, smart-home applications, robotics, and DIY electronics projects.

The sensor provides a simple digital output, making it easy to connect to Arduino, Raspberry Pi, ESP32, and other microcontroller platforms. When motion is detected within its sensing area, the output signal changes state, allowing a connected device or controller to trigger an appropriate action.
