The Xiaomi Smart Thermohygrograph 3 Pro, which just launched a crowdfunding campaign last week, is now available on e-commerce platforms such as JD.com. The retail price is 129 yuan, which is 15 yuan more than the crowdfunding price of 114 yuan.
IT Home has learned from the official source that this thermometer supports the detection of indoor temperature, humidity, and carbon dioxide concentration, helping users to stay informed about the air quality in real-time. The device is equipped with a Sensirion new generation low-power thermal conduction principle carbon dioxide sensor that continuously monitors the indoor carbon dioxide levels.
In terms of specifications, this device is equipped with a 3.6-inch LCD display screen, which provides clearer visuals. It supports the simultaneous display of date, day of the week, time, temperature, humidity, and carbon dioxide levels on the same screen.
At the same time, this device can be used in conjunction with devices that have a Bluetooth Mesh gateway, supporting Xiaomi's Mi Smart Connect technology. It can be linked to Xiaomi's air conditioners, air purifiers, curtains, and more. Additionally, you can use Xiaomi's App to view historical temperature and humidity curves, carbon dioxide concentration curves, and other data.
In addition, this product features a magnetic design that allows it to adhere to metal brackets, or it can be used by attaching a metal ring to a wall surface. It is also designed with low power consumption; a single CR2450 battery is sufficient for a standby period of about 1 year.
