Tuya WiFi/ZigBee Human Presence Sensor mmWave Radar Detection PIR Motion Sensor Smart Life APP Smart Home Security Protection Size: 100*100*35mm Detection signal: 24g millimeter wave radar Communication protocol: ZigBee/ Wifi Color: Black Power input: 5V1A Installation method: flat / ceiling mounted Specifications: Communication protocol ZigBee, it needs to be used with the gateway Function introduction Real-time detection of whether someone exists, micro-motion detection (heartbeat, breathing, etc.), motion detection Accurate detection of dynamic Static human presence This product uses advanced millimeter wave radar technology to accurately detect whether there are people in the areawhether they are moving or stationary Accurate recognition and wide range perception Subtle human or animal movements Built in multiple people and precision sensors, the presence of people in the room can be accurately identified through MFA intelligent algorithm. Conical detection range, applicable to room area of 6-25 square meters, induction angle of 90 degrees. The diameter of human sensing range is about 3m (installation height is 3m, ground projection) Intelligent linkage It can create intelligent scenes together with Tuya switches, lamps, curtains and other intelligent products to achieve energy saving, environmental protection, security alarm and other functions. With other intelligent devices, it can realize rich automation and scene control. Make intelligent hardware respond faster and control moresmoothly. It can still be used even if the network is disconnected. Difference from traditional human PIR infrared sensor PIR infrared sensors can only detect human motion, but cannot detect when people are still, and the false alarm is serious. The human presence sensor adopts the principle of radar microwave, and has the functions of human presence, human stillness, human micro-motion and human motion detection. Package Included: Human presence sensor xl, Instruction x1
