IT之家 news on September 30: The Xiaomi Smart Temperature and Humidity Meter 3 Pro, which just launched crowdfunding last week, is now available on e-commerce platforms such as JD.com, with a retail price of 129 yuan, 15 yuan more expensive than the crowdfunding price of 114 yuan.
IT之家 learned from official sources that this temperature and humidity meter can detect indoor temperature, humidity, and carbon dioxide concentration, helping users stay informed about air conditions in a timely manner. It is equipped with Sensirion's new-generation low-power CO2 sensor based on the thermal conductivity principle, continuously monitoring indoor CO2 concentration.
In terms of specifications, the device features a 3.6-inch large LCD display, making data clearer. It can simultaneously display the date, day of the week, time, temperature, humidity, and CO2 information on one screen.
In addition, the device can be used with devices equipped with a Bluetooth Mesh gateway. It is compatible with Xiaomi HyperOS Connect and can link with Mijia-compatible air conditioners, air purifiers, curtains, and more. Historical temperature/humidity curves and CO2 concentration curves can also be viewed through the Mi Home App.
Additionally, the device has a magnetic design, allowing it to be attached to metal brackets or mounted on walls with adhesive metal rings. With its low-power design, a single CR2450 battery provides approximately one year of standby time.
