1. Static human body recognition, automatic scene recognition, and anti false alarm processing 2. Multiple induction recognition, supporting mobile, micro-motion, heartbeat detection, high sensitivity detection, and ultra-low false alarms 3. The light recognition range is 0-2000lux, and the illuminance curve of the last can be checked, supporting intelligent linkage 4. Adjustable distance of 4.0-10 meters, sensitivity adjustable for 0-10 levels, suitable for various scenarios 5. It can be paired with an omnidirectional bracket, wall mounted, with adhesive backing that can be easily applied, suitable for living rooms, study rooms, bedrooms, restrooms, corridors, etc Please note:ZigBee Human Presence Sensor must be used with a ZigBee gateway! Otherwise it 't work! The millimeter wave radar human presence sensor, human presence sensor, has built-in millimeter wave human presence sensor and light sensing. It is based on millimeter wave technology, actively detecting movements, such as chest movements caused by human breathing and local movements of the human body, in order to achieve recognition and distance positioning of static human bodies. Compared to traditional infrared human body sensors, it can effectively avoid the awkwardness of "people turning off automatically while in the light".
