Features: 1. High precision. Sensors use top suppliers. The high precision of the measurement data can be guaranteed.2. Real-time monitoring and recording. The sensor is powered by USB. Compared to the battery version, sensors monitor temperature and humidity in real time. The sensor will report when the temperature and humidity change very little. You can check the value changes on the APP or the display. Changes in temperature and humidity are recorded on the APP and displayed to you using graphs.3. LCD display: The sensor uses LCD as temperature and humidity display, and adds time and date display on the screen. The time and date are automatically calibrated.4. Scene linkage: The sensor can be used as a temperature and humidity data source for Tuya Smart, Smart Life, , and Google Home. You can perform many automated processes based on data sources.5. Temperature unit switch: The sensor is designed with Celsius and Fahrenheit temperature display conversion. You can select the units you want to display according to your needs. voice support: The sensor supports , Google Home Assistant. You can check the current temperature and humidity by voice. supply: DC 5V/1A Mocro USBWi-Fi Support: 2.4G IEEE 802.11 b/gTemperature measurement range: 0-60Temperature accuracy: 1Humidity measurement range: 0%RH~99%RHHumidity Accuracy: 1%RHMaterial: ABScolour: WhitePackage Contents:1 x Temperature Humidity SensorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
