1. In addition to the movement of the human body induction sensitive, for the traditional scheme can not identify the micro-human body can also be sensitive induction; 2. Have good environmental adaptability, the induction effect is not affected by the temperature, brightness, humidity and light fluctuations and other surrounding environment; 3. Not easy to be affected by dirt, dust and other cover interference; 4. Can pass through the glass, plastic, ceramic, acrylic, rubber, wood board and other non-metallic materials; 5. The maximum induction distance is up to 3 meters; Support the hanging roof, hanging the wall and other installation methods; 57-64GHz ISM frequency band. Operational principle:The XKC-LD002 is a highly sensitive 57-64GHz human presence state sensor. Its working principle is to use FMCW frequency modulation continuous wave to detect the human body target in the set space. Combined with radar signal processing and accurate human body sensing algorithm, it can realize the highly sensitive human existence state sensing, can identify the human body in the motion and micro-motion state, and can calculate the distance of the target and other auxiliary information. Color: Black Material: plastic Package Contents: 1 x Super Sensitive Static Human Body Sensor Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
