Remind:   1. This sensor has no built-in battery. It needs USB power all the time.   2. The time and date display format cannot be changed.   Product Features:   1. High precision.   The sensor uses top suppliers. It can guarantee 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. LCD screen display   The sensor uses LCD as the display of temperature and humidity, and the display of time is added on the screen. Time are automatically calibrated.(Need Link WiFi)   4. Scene linkage   The sensor can be used as the temperature and humidity data source of Tuya Smart, Smart Life, Amazon Alexa, Google Home. You can do many automated processes based on the data source.   5. 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.   6. Third-party voice support.   The sensor supports Amazon Alexa, Google Home Asistant. You can check the current temperature and humidity by voice.   Product Parameter:   Power supply: DC 5V/1A Mocro USB   Wi-Fi Support: 2.4G IEEE 802.11 b/g/n   Temperature Measure Range: 0-60   Temperature Accuracy: ±1   Humidity Measure Range: 0% RH~99% RH   Humidity Accuracy: ±1% RH   App Support : Smart Life and Tuya Smart   APP Remote Monitor   When the sensor is registered to the APP and connected to the Internet, you can monitor the temperature and humidity of the room in real time anywhere in the world.   LCD Display   Display content   1. Temperature (/F switchable), humidity   2. Time (AM/PM , NO 24H). (Automatically adjust the time)   NOTE: Automatic time synchronization needs to be connected to the APP, and the network is always available.   Work with Amazon Alexa, Google Home   After connecting Amazon Alexa and Google home, You can query the current temperature and humidity by voice.   Real Time Monitoring & Historical Data Graph   1 Compared with batterybased sensors our sensors use USB power supply It does not have to worry about power saving strategies When the temperature changes by 03 degrees or the humidity changes by 2 the temperature and humidity will be reported to the service immediately. Our sensors are truly real-time monitor.   2. Historical data will be displayed by graph. The data is counted by day, month, and year.   and Switch   You can switch temperature unit between and . Just through press of the reset button one time.   Application Scenarios   You can install the sensor wherever you need (WiFi connection network is required).   Intelligent Linkage   High-precision and real-time monitoring help you complete different linkage strategies. For example, if the temperature reaches 32.
