Abstract
Carbon dioxide (CO2) is important factor of indoor air quality. In this paper we evaluate several CO2 sensors of latest generation. All sensors work on the same principle: nondispersive infrared (NDIR) detection. The sensors were evaluated in the campaign that lasted for several months. Good agreement between all sensors was observed, despite different construction, factory calibration and price. Finally, inexpensive method is proposed for continuous measurement of indoor concentrations of CO2.
