As part of the research entitled "Experimental determination of the optimal amount of air in a selected room in Ukraine based on measurements of carbon dioxide concentration", an experimental measurement was performed in a selected school room in Ukraine. The aim of the experimental measurement was to determine the course of air temperature, relative humidity and carbon dioxide concentration during the teaching process. From the carbon dioxide concentration curves, it is possible to calculate the required ventilation intensity in the room. This article documents the results of measuring the air temperature and the carbon dioxide concentration in the room, as well as the reactions of people in the room to the air quality.
