Why Monitor CO2 in Classrooms? -

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a high-level of indoor air quality, is to monitor Carbon Dioxide (CO2) levels within the classroom. Every time you exhale, you release CO2 into the air. Therefore, the CO2 level lets you determine if the room is being properly ventilated with fresh outside air; thereby, helping you gauge the quality of the air within that …

On the use of CO2 sensors in schools and other indoor ...

29/10/2020· A CO2 sensor measures the concentration of CO2 in the room, expressed typically in parts per million (ppm). A high CO2 concentration thus indicates poor air quality (1, 4) and the need to ventilate a room (3, 4). The measurement typically occurs continuously over time and requires no supervision. A wide range of CO2 sensors is available on the market. It is not the aim of this document to discuss the pros and cons of each, yet it is noted that NDIR (non-dispersive infrared) CO2 sensors …
