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 and date is added on the screen. Time and date are automatically calibrated. 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 Remind 1. This sensor has no built-in battery. It needs USB power all the time. 2. Time format cannot be switched. 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, date, day of the week. (Automatically adjust the time) NOTE: Automatic time synchronization needs to be connected to the APP, and the network is always available. Accurate Measurement NOTE: 1. After configuration, it will take 30 minuters to be accurate. 2. The Sensor reacts quickly, and even small environmental changes will be monitored Real Time Monitoring & Historical Data Graph 1. Compared with battery-based sensors, our sensors use USB power supply. It does not have to worry about power saving strategies. When the temperature changes by 0.3 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. 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 32.6 degrees Celsius, than turn on the air conditioner through our universal remote control. Or turn on the humidifier when the humidity is less than a certain value. APP Pages Real Shot Package Include Note: No power adapter included
