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

Unlike a CO2 sensor, a VOC sensor cannot indicate the rate of ventilation needed, only the level of VOCs in the air. It also cannot necessarily indicate whether safe or harmful concentrations of VOC contaminants are present. It can indicate a general change in the concentration of contaminants. This makes air quality sensors a better solution in applications where unusual, non-occupant-related ...

VOC Sensors - Belimo

1 VOC Sensors What are VOCs VOC is an abbreviation for Volatile Organic Compounds and a col-lective term for gaseous carbonaceous substances. Depending on how high the concentration of these substances in the ambient air is, we can perceive them by smelling them with our nose. On average, a person inhales about 15 kg of air per day, 80% of it in-doors. Outside air quality is routinely ...

MOS sensors to measure VOC for ventilation control

The application of Metal Oxide Semiconductor (MOS) sensors measuring Volatile Organic Compounds (VOC) gains increasing attention in the ventilation community because of their low price and claimed ability to supplement or even substitute CO 2 sensors for demand controlled ventilation (DCV). Even though there are many “Indoor Environmental Quality” meters available on the market, in which ...

VOC Sensing With AI Signal Processing Based On Sensor Fusion

VOC sensors are used to measure the increase in concentration of volatile organic compounds. These work in part on the photoacoustic sensor principle. Here, a plate coated with substrate is heated by the use of a heat plate in the sensor. Through this process, the molecules in the air are made sensitive and react with the plate. This results in sound waves generated by thermal expansion. These ...
