The perfect companion for indoor environments allowing you to monitor CO2 levels, temperature, relative humidity and atmospheric pressure
Monitoring CO2 is smart

Tired and can't concentrate?
Ever feel tired and drowsy in a room? Can’t focus and head feels heavy? Your air quality might be to blame. Namely, the CO2 level.
High Co2 levels decrease productivity
According to Harvard research, high CO2 levels can decrease your productivity, cognitive abilities and general wellbeing. For example, if the CO2 concentration in the room exceeds 1000 parts per million, your cognitive function decreases by 15%. Worse yet, if CO2 levels reach 1400 ppm, your cognitive abilities drop by a staggering 50%.


Co2 level as a proxy for ventilation quality
Monitoring CO2 in public spaces helps to encourage proper ventilation. CO2 is a gas produced when we exhale. So, the higher CO2 in the room, the more you’re breathing air that someone else has already exhaled. Therefore, monitoring CO2 levels provides warnings about the air quality deteriorating.
