1. High precision. The sensor uses top suppliers. It can the high precision of the measurement data. 2. Real-time monitoring and recording. The sensor uses USB power supply. Compared with the battery version, the sensor will monitor the temperature and humidity in real time. The sensor will report when the temperature and humidity changes very little. You can view the changes in the value on the APP or display screen. Record the temperature and humidity changes on the APP, and use the graphics to show you. 3. Large LCD screen display. The sensor uses LCD as the display of temperature and humidity, and the display of time and date is added on the screen. Time and date are automatically calibrated. 4. BlackLight Supported. When the object pass by the infrared sensing window from distance less than equal 5cm, the screen will light up for about 10s 5. Scene linkage. The sensor can be used as the temperature and humidity data source of Tuya Smart, Smart Life, , Home. You can do many automated processes based on the data source. Temperature Unit Switch. The sensor is designed with a temperature display conversion function of Celsius and Fahrenheit. You can choose the unit that needs to be displayed according to your needs. Two installation methods: a) Use the built-in bracket and place it directly on the desktop b) Use the hook and hang it (the hook is included in the package) voice support. The sensor supports for , for Home Asistant. You can check the current temperature and humidity by voice.
