Features and Specifications
The Smart Temperature and Humidity Monitor 3 Mini seemingly carries the same functions as its predecessor. It can measure temperatures in your house ranging from 0°C to 60°C (about 32°F to 140°F), displaying the readings to the nearest 0.1°C (approximately 0.2°F). Additionally, it can measure humidity levels within a spectrum of 0-99% relative humidity (RH).
This smart gadget utilizes Bluetooth Low Energy (BLE) 5.0 and is expected to last for roughly three years on the included CR2450 battery. When connected with other smart home devices, it can activate heaters, air conditioners, or dehumidifiers based on certain conditions. Users can also monitor data logs through the Xiaomi Home app.
Design and Differences
As hinted by its name, the new model is designed to be more compact. The Mini version has dimensions of 53.0 x 45.3 x 13.0 mm (approximately 2.1 x 1.8 x 0.5 inches) and weighs 30 g (around 1.1 oz). In comparison, the original version is larger, measuring 79.6 x 70.2 x 14.5 mm (nearly 3.1 x 2.8 x 0.6 inches) and weighing 72 g (about 2.5 oz). Another notable distinction is the maximum power, which is increased to 51 mW for the Mini. Moreover, it lacks a stand, unlike the standard Smart Temperature and Humidity Monitor 3.
Availability and Pricing
It’s still uncertain when the Xiaomi Smart Temperature and Humidity Monitor 3 Mini will be available globally. For reference regarding its price, in European countries such as Germany, the Xiaomi Smart Temperature and Humidity Monitor 3 sells for €14.99.
