The HC-SR501 PIR Motion Sensor is a widely used module designed to detect infrared radiation (IR) emitted by the human body. It is often used in motion detection systems for security, automatic lighting, and energy-saving applications. The sensor works by detecting changes in the IR radiation in its field of view. Once motion is detected, the sensor sends a signal to a microcontroller or external device. The module is easy to use and can be powered with 5V DC, featuring adjustable sensitivity and delay time. This sensor is compact, reliable, and commonly used in security systems, automatic lighting, and home automation projects.
