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 ...
