The PIR Motion Sensor Detector Module HC-SR501 is designed to detect motion, primarily the movement of a human body within its range. It’s commonly known as a “PIR,” “Pyroelectric,” “Passive Infrared,” or “IR Motion” sensor.
This module features an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It includes a potentiometer for adjusting delay time and another for sensitivity. It is compatible with platforms such as Arduino, Raspberry Pi, AVR, PIC, and 8051, making it versatile for various applications.

The PIR Motion Sensor Detector Module HC-SR501 is a versatile pir / ir and optical sensor used across a wide range of applications including motion detection, security systems, automatic lighting, people counting, and gesture recognition.
Common use cases:
Building an automatic porch light
Creating a people counter for a room
Adding motion detection to a security system
This product is ideal for home automation builders and security system designers.
Technical Tip: PIR sensors detect heat-emitting movement. Adjust sensitivity and delay potentiometers for your environment. False triggers can be reduced with proper shielding.
