And thanks to the mobile application you can monitor the air quality also on your smartphone.

Monitor the CO2 level in the entire interior with your mobile phone
CO2 is a gas that is naturally found in the air but is also part of human metabolism. It is released during exhalation, and if there are many people in the room at once, for example, in school classrooms or open space offices, its level can rise very quickly.

The amount of CO2 in the room then gets to the point that impairs the ability to concentrate and causes fatigue. At this point, it is important to ventilate.

Various solutions for regular and efficient ventilation in enclosed rooms are currently being tested. In Germany, for example, modules equipped with CO2 sensors have been used to measure air quality in school classrooms.

The advantage of the CO2 monitor is that it is easy to use, intuitively understandable thanks to the traffic light system and measures with high accuracy.  The air quality meter ensures regular and efficient ventilation.

In addition to increasing the ability to concentrate, there is also a reduction in the risk of transmitting various viruses, another positive effect of indoor air quality monitoring.
