Note: The T&H ZigBee Tuya smart sensor should work with the Tuya Hub gateway which supports the ZigBee protocol. It can't work without Tuya ZigBee smart gateway. Features: * The T&H sensor detects the temperature and humidity in the environment over time, and the LCD screen dynamically displays real-time values (TEM., Hum., Battery capacity, signal WIRELESS). provide us with comfortable temperature and humidity. * With gateway and home cloud platform, perception of temperature and humidity changes and real-time reporting to users' phone. You can see current and historical temperature and humidity data. * APP remote control link scene, when the temperature and humidity detector control temperature is too hot, it link with home automation to control air conditioner or turn off. *You can connect the sensor with intelligent output, if the detected humidity is too low, it can turn on the output and power of the humidifier. *It can also be combined with other devices to design and implement intelligent application scenarios. Ultra-fast response, anti-interference ability, ultra-low power consumption and cost-effective. *Easy to installation, installation by screw gluing or double-sided easy fixed on the wall.
