RCWL-0516 Microwave Radar Sensor Module – Human Motion Detection, 3.3V–5V, High Sensitivity, Ideal for IoT and Automation Projects

Description RCWL-0516 Microwave Radar Sensor Module – Human Motion Detection, 3.3V–5V, Ideal for IoT and Automation Projects The RCWL-0516 Microwave Radar Sensor Module is a highly sensitive motion detection sensor that uses microwave Doppler radar technology to detect human movement. Unlike traditional PIR motion sensors, this module can sense motion through walls, glass, or plastic, making it perfect for home automation, lighting control, security, and IoT projects. Operating in the 3.2GHz to 3.4GHz ISM band, the module emits microwave pulses and detects phase shifts from moving objects. This offers more consistent performance in environments where infrared sensors struggle. It’s compatible with popular platforms like Arduino, ESP32, Raspberry Pi, and other microcontrollers, with a simple digital output that directly integrates with your circuits or automation systems. �� Key Features: Microwave Doppler radar motion detection Detects motion through plastic, glass, and wood Longer range than typical PIR sensors Digital output HIGH when motion is detected Compatible with 3.3V and 5V logic Ideal for embedded and IoT applications �� Technical Specifications: Operating Voltage: 4–28V DC (5V optimal) Detection Range: 5–7 meters Output Voltage (HIGH): ~3.3V Current Draw: ~3mA Output Duration: ~2 seconds (can be modified) Frequency: 3.2–3.4GHz Size: 35mm x 17mm �� Use Cases & Applications: Smart lighting with motion-activated switching Security systems for homes and offices IoT-based motion alerts Occupancy detection in rooms or corridors Retail footfall tracking Hidden sensors behind panels, plastic, or furniture �� Why Buy from DeviceBay?
