The SR602 Infrared Motion Detection Sensor Module is a compact and highly sensitive PIR (Passive Infrared) sensor designed for accurate motion detection in security, automation, and lighting applications. Operating on a low voltage of 3.3V–5V, it easily interfaces with popular microcontrollers such as Arduino, Raspberry Pi, and ESP32. The SR602 detects human movement up to 5 meters away, producing a high-level output signal when motion is detected. With ultra-low power consumption (only 20µA) and fast response time, it’s perfect for battery-powered devices. The module also allows adjustment of output delay time (from 2.5 seconds to 1 hour), enabling flexible integration into various projects. Its repeatable trigger mode ensures continuous motion detection without resetting. Widely used in motion-activated lighting, alarms, automatic doors, and industrial automation, the SR602 offers reliable performance in a miniature form factor. Featured By RoboticsBD.
