CO2 Sensors vs. VOC Sensors for IAQ - What's the ...

Most IR carbon dioxide sensors only measure CO2. A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air. Whereas outside air carbon dioxide levels tend to be relatively low and constant, an indoor CO2 measurement can be used to determine whether a room or building is occupied. In other words, higher levels of CO2 ...
