Note: The smart Tuya T&H sensor must work with Tuya gateway Hub which supports protocol. It can't work without Tuya intelligent gateway.Features:*The T&H sensor detects temperature and humidity in the environment in time, and LCD screen dynamic display real-time values(tem., hum., battery capacity, WIFI signal). Providing us with comfortable temperature and humidity. *With the gateway and cloud platform docking, perception of temperature and humidity changes and real-time report to the users phone. You can view current and historical temperature and humidity data.*APP remote control linkage scene, when temperature and humidity detector check temperature is too hot, it will linkage with home automation to control air-conditioner on or off.*You can connect the sensor with smart outlet, if the humidity detected is too low, it can turn on the outlet and power the humidifier.*It can also be combined with other devices to design and implement smart application scenarios. Ultra-fast response, anti-interference ability, ultra-low power consumption and cost-effective. *Easy to installation, install by screw or double-sided adhesive to easy fixed it on the wall.Specifications:Type: T&H SensorPower Supply: 2*AAA (not included) Relative Humidity Sensor: 3% RH (max)High Accuracy Temperature Sensor: 0.3C (max)0 to 100% RH operating rangeUp to -40 to +85C operating rangeColor: WhiteMaterial: ABSItem Size: 68*68*30mmItem Weight: 72gPackage Size: Approx. 10*9*6cm/3.9*3.5*2.4inPackage Weight: Approx. 85g/3oz Packing List:1 * Temperature&Humidity Sensor
