The Gravity Occupancy Sensor uses 24 GHz FMCW radar technology, enabling precise presence detection at a distance of up to 8 meters and movement and distance measurement up to 12 meters. Thanks to its high resistance to environmental interference, it works reliably regardless of light, temperature or dust, effectively detecting both static and dynamic objects. Compatibility with Arduino, ESP32, Raspberry Pi and a simple Gravity interface make it an ideal solution for intelligent lighting, building automation and security systems. DFRobot SEN0610
