Review on Air Quality Monitor Xiaomi Smartmi PM 2.5 Air Detector by Jhalak Tamrakar ᠌

When using it, I was convinced that using non-distilled (even softened by a filter and boiling) water in ultrasonic air humidifiers is a bad idea due to the significant amount of dust produced by such devices Some pros: Compact, easy to use, you can change the brightness of the backlight (if you know Chinese or accidentally discover this functionality, because the manual is only in Chinese) Different cons: The main drawback is that there is no normal manual at least in English, therefore it is completely unclear, for example, what units of measurement the values ​​output by the device have. Even without a manual, it is not obvious that spontaneous shutdown of the device after half an hour without an external power source is the norm (as I was convinced by finding the English-language manual for another model of this device). Also sad is the lack of a power cable in the kit (this is a regular usb cord, but it could have been put). The decision to make a power connector on the top surface of the device is sheer insanity: thanks to this design, it is almost impossible to arrange it so that nothing interferes.
