Why Monitor CO2 in Classrooms?

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a highlevel 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 ...
