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 ...

CO2 Control In School Classrooms - sensors for commercial ...

carbon dioxide (CO 2) sensors in each zone control the outdoor air damper for that zone. If background (outdoor) CO 2 levels are detected, dampers would remain closed. However, if elevated CO 2 levels occur, indicating occupancy, dampers would open until the CO 2 levels return to background levels. Use of such a demand controlled ventilation system in these circumstances can help ensure …
