Tuya ZigBee Smart Human Presence Sensor Micro-motion Detect Human Motion Features: Communication protocol：ZigBee, which needs to be connected with networking gateway Function introduction：Real-time detection of human presence, micro-movement detection (head off, waving, lifting, turning, brushing the phone, flipping books, etc.), motion detection (walking, trotting, running fast, turning in circles, jumping and other movements) Accurate detection of dynamics： Static human presence Static human presence This product uses advanced 5.8GHz millimeter wave radar technology to accurately detect whether there are people in the area, whether they are moving or stationary. Accurate identification, wide range of perception Subtle human or animal movement Built-in multi-person and sophisticated sensors, the intelligent algorithm can accurately identify whether there is someone in the room. Conical detection range with a sensing angle of 110 degrees Human micro-motion sensing radius is about 2m, motion sensing radius is 5m (installation height is 2-6m, ground projection). Intelligent linkage：It can create intelligent scenes with Tuya switches, lamps, curtains and other intelligent products to achieve energy saving, environmental protection, security alarm and other functions. Cooperate with other intelligent devices to realize rich automation and scene control. Make smart hardware react faster and control more smoothly. Even if the network is disconnected, it can still be used. Difference with traditional human PIR sensor：PIR infrared sensors can only detect human movement, but not when the person is stationary, with serious false alarms. Human presence sensor uses the principle of radar microwave, with human presence, human stationary, human micro-motion and human motion detection Specification: Zigbee USB Human Presence Sensor Compatible with Tuya smart or Smart life app Millimeter Wave Radar Detection Radar frequency: 5.8G Detect angle: 110° Detect distance: 0-10m Power supply: Mini USB , 5V-1A Wireless Type2.4GHz Protocol: Zigbee Operating Temperature: -10°C~ 55°C Operating Humidity: 0% ~ 95% (non-condensing) Support systems: Android and IOS Product size(D*W*H): 72x 72x 31mm Package Included: 1*Sensor 1*Manual 1*Connection cable Note: 1.
