Xiaomi sensors are known for their extremely sensitive sensors and small size. The air quality presented is precisely tested, and the accessory itself can be positioned in the room to immediately start detecting ambient pollution. What exactly does the Xiaomi air quality sensor measure and how do you read the data on the display?
Xiaomi air quality sensor - what does it measure and how does it work?
The air quality sensor is a pocket-sized detector of PM2.5. Thanks to the use of laser measurement technology, the device is able to measure ambient parameters, taking into account aspects such as humidity and temperature levels and smog condensation. The product unfortunately does not measure atmospheric pressure. The Xiaomi Air Quality Sensor helps to determine the level of pollution, being an extremely useful device for allergy sufferers and people with respiratory diseases. Before leaving the house, it can warn the owner of elevated concentrations of harmful PM2.5 dust.
Highlights of the Xiaomi air sensor
Among the most important features of the air quality meter is its exceptional sensitivity to changes in the environment and its ability to quickly identify pollution levels. The device's battery capacity is 950 mAh, and the ability to combine the sensor with Xiaomi purifiers makes it much easier to take care of your own health. What's more, the device switches off after 30 minutes of operation, thus saving energy.
Xiaomi air quality sensor mode and price
The air quality determinant refers to the standards of the brand's country of origin, so when reading the information that appears on the LCD display, there are some important facts to keep in mind to help understand the mechanism of the Xiaomi device. The sensors are not customisable, so pollution thresholds applicable in Europe cannot be set.
Chinese smog concentration standards indicate that dust levels of 75 μg/m³ count towards the permitted lower level, while European standards consider exceeding 35 μg/m³ to be entering moderate air quality levels. The display shows the exact ambient parameters in real time, thanks to the extremely sensitive sensors built into the device.
A line runs through the display, which changes colour according to the three levels distinguishable in the PM2.5 sensor from Xiaomi:
- Green indicates up to 75 μg/m³
- Orange indicates exceedance of moderate levels from 76 μg/m³ to 150 μg/m³
- Red colour is displayed when 150 μg/m³ is exceeded
The device, which is the size of a small smartphone, is powered by a rechargeable battery with a cable with a micro USB plug. The package includes an instruction manual and the meter itself, but you will not find a Xiaomi charger. The smog sensor can be purchased for as little as £149. Devices that measure pollution go hand in hand with Xiaomi purifiers and even humidifiers. The air sensor allows you to see if you will need the other two machines, which will significantly improve the ambient air quality.
