Description
The HC-SR501 PIR Motion Sensor Module is a compact and reliable passive infrared sensor designed to detect movement from people and other warm-bodied objects. It uses infrared radiation changes within its detection area to trigger a digital output signal, making it easy to integrate with microcontrollers and electronic control systems.
The module features adjustable sensitivity and time-delay controls, allowing users to customize the detection range and how long the output remains active after motion is detected. Its compact design and simple interface make it suitable for Arduino and other DIY electronics projects, including automatic lights, security alarms, smart-home systems, and motion-activated devices.
