Laboratory Evaluation of Low-Cost Air Quality Sensors

· VOC SENSORS TESTING ... If a device presents as a multi-pollutant sensor box, then the cost per pollutant type (individual sensor) should be less than $2000. Sensors are first evaluated in the field at one of SAQMD’s fixed air monitoring stations for two months. Depending on the field testing results, sensors, which have shown acceptable performance (correlation coefficient R2 > ...

Accurately Measuring Volatile Organic Compounds (VOC’s ...

drawn into the sensor chamber (see diagram below). When hit with this UV light, most VOC molecules, with the exception of low molecular weight VOC’s, will break up into free electrons and positively charged ions, a process called ionization. This ionized gas is electrically charged and produces an electric current. The ion current is collected by the sensor, ampli˛ed and converted to a ...
