Last week, the Xiaomi Smart Temperature and Humidity Monitor 3 Pro, which had just started its crowdfunding campaign, is now available on e-commerce platforms such as JD.com. Its retail price is 129 yuan, which is 15 yuan more than the crowdfunding price of 114 yuan.

According to official information, this temperature and humidity monitor supports detecting indoor temperature, humidity, and carbon dioxide concentration, helping users stay informed about air conditions in a timely manner. It is equipped with a new-generation low-power carbon dioxide sensor from Sensirion based on thermal conductivity, continuously monitoring indoor carbon dioxide levels.

In terms of specifications, the device features a 3.6-inch large LCD display, making data clearer. It supports displaying the date, day of the week, time, temperature, humidity, and carbon dioxide information on the same screen. At the same time, it can be used with devices that have a Bluetooth Mesh gateway and supports Xiaomi HyperOS Connect, allowing linkage with Mijia-compatible air conditioners, air purifiers, curtains, and more. Users can also view historical temperature and humidity curves, carbon dioxide concentration curves, and more through the Mijia App.

In addition, the product adopts a magnetic design, so it can attach to a metal stand or be used on a wall with an adhesive metal ring. It uses a low-power design, and a single CR2450 battery can provide about 1 year of standby time.
