Function introduction: Real-time detection of whether or now not somebody exists, micro-motion detection (heartbeat, breathing, etc.), motion detection Accurate detection of dynamic: This product uses progressed millimeter wave radar technology to precisely locate whether or not or not there are people within the area,whether they are moving or stationary. Accurate reputation and wide range perception subtle human or animal movements. Built in several humans and precision sensors, the presence of people in the room would be precisely recognized by way of manner of MFA clever algorithm. Conical detection range, relevant to room subject of 6-25 sq. meters, induction perspective of ninety degrees. The diameter of human sensing differ is able 3meter (installation peak is 3meter, ground projection) Intelligent linkage: It can create clever scenes along with Tuya switches, lamps, curtains and different clever products to achieve energy saving, environmental protection, security alarm and varied functions. With diverse intelligent devices, it will perceive rich automation and scene control. Make intelligent hardware respond faster and management moresmoothly. It can however be used even if the network is disconnected. Difference from standard human PIR infrared sensor: PIR infrared sensors can completely find out human motion, but can't find out when persons are still, and the false alarm is serious. The human presence sensor adopts the main of radar microwave, and has the purposes of human presence, human stillness, human micro-motion and human movement detection. Smart home platform: Tuya Feature: Micro-motion Detect Human Motion Detector Size: a hundred x 100 x 35mm Detection signal: 24g millimeter wave radar Power input: 5v1a Installation method: flat / ceiling fixed Communication protocol: ZigBee color:Black Material:plastic Package Contents: 2 x Human Presence Sensor Only the above equipment content, other item usually are not included. Note: Light reflection and different displays could cause the color of the object within the photograph somewhat different from the real thing. The size allowed error is +/- 1-3cm.
