Description

The HC-SR501 PIR Motion Sensor Module is a highly reliable infrared-based motion detector that detects human movement using passive infrared (PIR) technology. It’s one of the most popular motion sensors for Arduino, Raspberry Pi, ESP32 , and other microcontroller platforms. This module detects changes in infrared radiation emitted by moving bodies within its range and outputs a digital HIGH signal when motion is detected. It features adjustable sensitivity and delay time , making it versatile for a variety of DIY electronics, security systems, and automation projects . Encased in a protective plastic housing , this sensor offers stable performance, easy installation, and excellent immunity t
