The RCWL-0516 microwave Doppler radar motion sensor module is a compact radar motion sensor that detects moving objects using microwave Doppler sensing, making it a useful alternative to PIR sensors in electronics projects. Built around the popular RCWL-0516 design, it provides simple motion-trigger capability for Arduino, Raspberry Pi, ESP32, and other GPIO-based controllers in automation, security, lighting, and robotics builds. Because it senses motion with radar rather than infrared, it is well suited to prototyping smart switches, occupancy-style triggers, and concealed motion detection behind non-metallic enclosures.
