The sensor detects particles (PM2.5) in the air. It cannot detect gases/odours.
PM2.5 are small inhalable particles, that measure 0.1-2.5 micrometres.


There is no on/off switch. To turn it on, just plug it in and wait a few seconds.
After plugging it in, the indicator light will start to flash from green to yellow to red. When the flashing stops, the sensor is ready to use.

This sensor checks the air quality by detecting particles (PM2.5) in your home.
Use your own power cord and adapter to easily turn on and use the sensor. You just need to connect it to a USB-C cable and wait a few seconds.
A light indicates 3 levels of air quality – green (good), yellow (ok), and red (not good).
Recommended to combine with FÖRNUFTIG air purifier. When the air quality is not good in your home, turn on FÖRNUFTIG air purifier to enjoy a good level of indoor air quality.
Place it in the living room, bedroom or other rooms where you spend a lot of time. With its small size, you can easily move it from room to room so you can rest assured that the air quality is good.
Works just as well in small and large rooms, since the air quality is usually similar throughout a room.
