Enhance your security and automation projects with the RCWL-0516 Microwave Motion Sensor Module. This high-sensitivity Doppler radar sensor detects human motion with greater accuracy than traditional PIR sensors. Designed for contactless detection, it works through non-metallic surfaces such as plastic, glass, or wood, making it ideal for hidden or discreet installations. ✅ Key Features: Doppler Radar Technology: Provides accurate motion detection with fewer false triggers compared to PIR sensors. Long Range Detection: Senses movement within a 3–7 meter range with a wide detection angle. Penetrates Non-Metallic Surfaces: Detects through plastic, glass, and wood, making it perfect for concealed applications. Low Power Consumption: Operates on 3.3V–5V with minimal power draw, ideal for battery-powered projects. Wide Compatibility: Works with Arduino, Raspberry Pi, ESP32, and other microcontrollers.
