Tuya Smart ZigBee/WiFi Human Presence Detector mmWave Radar Detection Sensor Light Luminosity 2 in 1 Function Smart Life APP Ceiling Mount Human Body Sensing Detection Motion PIR Hub Required By MOESMain Features:1 ZigBee Smart Human Presence Sensor:Featured as human presence,human static,human micro motion and human movement movement detection to locate the presence or absence of folk in the area,even to locate the static state akin to workforce slumbering precisely with mmWave Radar Detection featured Light Intensity for SmartScene Linkage:Illuminance visible reveal unit in Tuya Smart APP permits its smart feature as intelligent scene linkage with different clever devices,especially your home lighting fixtures to ON/OFF mechanically because the brightness changes;Besides,you can intelligently linkage the sensor to other smart home devices for home automation Hub as Control Center:Tuya ZigBee gateway is needed for this ZigBee human presence sensor,performing because the center bridge for all Tuya ZigBee wise instruments with extremely secure sign and necessity for whole-house intelligence.(note:Tuya ZigBee hub is incredibly counseled for its wider compatibility than different hubs)4 New Design with Multiple Settings:Set the sensitivity from 1-9 by yourself need,together with minimal hit upon fluctuate as 0 and maximum as 9 for flexible detection demand,it is designed with hold time set as 0-1500s and detection latency set as 0-10s to avoid beside the point anxious movement and reduce false alarm rate APP Interface for Simple Application:Tuya Smart APP well suited ensures its wireless remote control anyplace you like,monitoring your house security wherever and each time with corresponding target distance display in APP;Ceiling-mounted installation;includes complete 2-year warrantly and 60-day refund warrantly for total satisfaction:Product name: Human presence sensor Wireless Technology: Zigbee Work voltage: AC100V-250V Work current: ≤70mA Work temperature: -20℃~+70℃ Sensitivity: 0-9 (Default 7) Detect distance: 0~9m (Default distance 7 m) Delay time: 1. goal detection confirmation time: 0~0. 2. target disappearance put off time: 20s~25min. It is recommended to not be lower than 15 seconds. If too small, clean to miss. Light sense: 0~2000Lux Installation mode: Ceiling Product size: ∅93x30 Microwave operating frequency: 5 Microwave transmitting power: 3-5dBm Module Model: ZT3L Model Max RF Power: +10dBm Operating Frequency: 2 Package list:Human presence sensor*1User manual*1 User manual: QA:1:Does it choose hub for wise controls in APP? A:Yes,it is produced with ZigBee protocol which is Tuya ZigBee hub required:Can I set the detection latency to reduce false alarm rate?A:Yes,you can set the detection latency from 0 to 10s to circumvent irrelevant demanding movement:Can I set the hold time to guarantee its preferrred detection function?A:Yes,there is the hold time set accessible in APP for a lot extra appropriate detection:What is the illuminance for in APP?A:It is the operate for the sensor which will video display real-time luminance with its smooth sense as 0-200Lux:What is the deference between a human presence sensor and a PIR movement sensor?A:The intelligent human presence sensor acts as extra sensitive and with more mandatory elements in APP to explain the meaning of domestic safety in a genuine sense than a PIR motion sensor,even can accurately hit upon the static state equivalent to crew sleeping.
