The RCWL-0516 Microwave Radar Sensor Module<\/a><\/strong> is a highly sensitive motion detection sensor that uses microwave Doppler radar technology<\/strong> to detect human movement. Unlike traditional PIR motion sensors<\/strong><\/a>, this module can sense motion through walls<\/strong>, glass, or plastic, making it perfect for home automation<\/a><\/strong>, lighting control, security, and IoT projects<\/a><\/strong>.<\/p>\n Operating in the 3.2GHz to 3.4GHz ISM band<\/strong>, the module emits microwave pulses and detects phase shifts from moving objects. This offers more consistent performance in environments where infrared sensors struggle.<\/p>\n It\u2019s compatible with popular platforms like Arduino<\/a><\/strong>, ESP32<\/a><\/strong>, Raspberry Pi<\/a><\/strong>, and other microcontrollers<\/a><\/strong>, with a simple digital output that directly integrates with your circuits or automation systems.<\/p>\n Microwave Doppler radar motion detection<\/p>\n<\/li>\n Detects motion through plastic, glass, and wood<\/strong><\/p>\n<\/li>\n Longer range than typical PIR sensors<\/strong><\/a><\/p>\n<\/li>\n Digital output HIGH when motion is detected<\/p>\n<\/li>\n Compatible with 3.3V and 5V logic<\/p>\n<\/li>\n Ideal for embedded and IoT applications<\/a><\/strong><\/p>\n<\/li>\n<\/ul>\n Operating Voltage<\/strong>: 4\u201328V DC (5V optimal)<\/p>\n<\/li>\n Detection Range<\/strong>: 5\u20137 meters<\/p>\n<\/li>\n Output Voltage (HIGH)<\/strong>: ~3.3V<\/p>\n<\/li>\n Current Draw<\/strong>: ~3mA<\/p>\n<\/li>\n Output Duration<\/strong>: ~2 seconds (can be modified)<\/p>\n<\/li>\n Frequency<\/strong>: 3.2\u20133.4GHz<\/p>\n<\/li>\n Size<\/strong>: 35mm x 17mm<\/p>\n<\/li>\n<\/ul>\n Smart lighting<\/a><\/strong> with motion-activated switching<\/p>\n<\/li>\n Security systems<\/a><\/strong> for homes and offices<\/p>\n<\/li>\n IoT-based motion alerts<\/a><\/strong><\/p>\n<\/li>\n Occupancy detection in rooms or corridors<\/p>\n<\/li>\n Retail footfall tracking<\/p>\n<\/li>\n Hidden sensors behind panels, plastic, or furniture<\/p>\n<\/li>\n<\/ul>\n At DeviceBay, every RCWL-0516 module is tested for accuracy and reliability<\/strong>.
