Indoor Air Quality by CO2 Monitoring | CO2 Sensors ...

CO 2 sensors measure the amount of CO 2 in the air and send a signal to a ventilation device or variable air volume system (VAV). They then control individual fan damper valves to adjust ventilation levels. Of course, air is not composed of CO 2 alone. Ventilating rooms also reduces the number of viruses and bacteria, improved indoor air quality.
