Introduction: Based on the principle of Doppler radar, the detection of motion, fidget and rest can be realized. The product is positioned as the application of perception scene, the perception range: 10-30cm (adjustable, short range light scanning), 0.8-2m (adjustable, close sensing), wall-mounted or embedded installation, and the perception Angle: 110°±10°, with the ability of photosensitive detection (no light sensor device, need external connection), pin insertion type or table paste compatible design, meet the static and motion state detection of life, in the lighting system, realize the combination of human lamp, energy saving and emission reduction.
