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

+

People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the shortterm, random drift found in air quality sensors. Most IR carbon ...

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

+

As a control, a CO2 sensor can activate an alarm or mitigation strategy (activate filters or ventilation). Because carbon dioxide is an inert gas, it is one of the few elements that will not cause an air quality sensor to react. Both approaches can be applied to a demandcontrolled ventilation strategy, but the results may be very different.
