The HC-SR501 PIR Motion Sensor Module is a widely used sensor designed to detect human body movement using infrared radiation. It is commonly used in security systems, automatic lighting, smart home devices, and IoT projects.
This sensor works by detecting changes in infrared radiation emitted by moving objects such as humans or animals. When motion is detected, the module outputs a digital HIGH signal, which can be easily read by microcontrollers like Arduino, ESP32, or Raspberry Pi.
The HC-SR501 module features adjustable sensitivity and delay time, allowing users to customize the detection range and trigger duration according to their project requirements. Its low power consumption and reliable performance make it ideal for continuous monitoring applications.
With its easy interface and simple three-pin connection (VCC, GND, OUT), the HC-SR501 PIR sensor is perfect for DIY electronics, robotics, motion-activated lights, security alarms, and automation systems. 🚶♂️💡
