Features: *Precision: Built-in temperature and humidity sensors. Temperature sensor - 20 ° C to 60 ° C, humidity sensor 0% RH to RH. The temperature is accurate to 1 ° C and the humidity is accurate to 5% RH. And updates every two minutes to achieve higher accuracy. *Monitoring: Digital humidity thermometers can be easily monitored remotely in intelligent living applications. When the environment changes, intelligent links can be made. For example, when the room temperature exceeds 35 ° C. The air conditioner will automatically turn on, or if the humidity drops below 20% RH, the humidifier will spray out. *Automation: You can ask about the temperature and humidity of the greenhouse through an assistant intelligent speaker. For example, "What is your temperature, please?"? *Free data storage and export: The indoor hygrometer supports year-round data export and in-application data storage. Using a smartphone, you can quickly and easily download logs and then export them as CSV files via email. *Compact and portable design: Our smart thermometer with humidity sensor has a size of 70 x 24 x 20mm, which saves space and is easy to carry. *Note: You need to use the zigbee gateway together Specifications: *Product parameter：DC3V LRO3 *Quiescent current：≤10uA *Alarm current：
