The Xiaomi Mijia Bluetooth Thermometer 3 (MJWSD05MMC) is a smart device that refreshes and senses changes in temperature and humidity every six seconds, thanks to its built-in industrial-grade Swiss Sensirion high-precision digital temperature and humidity sensor. The sensor can detect 0.1 °C temperature fluctuations and 1%RH humidity changes. The device features a 62.6 mm x 53.2 mm LCD screen, displaying data in different segments, including temperature, humidity, time, date, and the day of the week. The date and time are received from the Bluetooth-paired device. Powered by a CR2450 battery, the Mijia Smart Thermometer 3 can operate for 1.5 years on a single battery. It also has two buttons on the side, with the upper button allowing users to change the screen display.
