VOC Sensors: Volatile Organic Compounds Sensor | GDS …

VOC sensors use a bright ultraviolet light source to knock electrons out of the VOC molecule; the electrons are measured and their flow indicates that VOC molecules are present at the sensor. Each specific type of VOC molecule has an ‘ionization potential’ (IP) value that represents the amount of energy necessary to liberate an electron; this value is measured in ‘electron volts’, or ...


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, nonoccupantrelated ...
