Reliable HC-SR501 PIR Motion Sensor Module with adjustable sensitivity and delay, designed for Arduino and Raspberry Pi. Detects human movement using infrared technology with up to 7m range, low power use, and includes a protective case for easy installation.
Product 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 to environmental interference.
