What''s the Difference between CO2 Sensors and VOC Sensors

20180701· For example, while a CO2 sensor usually requires frequent checks by engineers and maintenance technicians, a VOC sensor generally requires little if any calibration be done manually. For a CO2 sensor, this often has to do with automatic baseline calibration, which focuses on indoor air quality. By using ABC, engineers recalibrate the sensors periodically …


Uncovering the Airthings carbon dioxide sensor

VOC sensor: Alternatively, many volatile organic compound (VOC) sensors are often used to measure CO 2. Through a complex formula, the results are calculated based on the presence of VOC’s in the air. This option is often preferred if a device does not have space or means to install a sensor that is specifically designed to measure CO 2. Chemical carbon dioxide sensors: …


What''s the Difference between VOC Sensors and CO2 Sensors ...

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, …
