Portable air pollution sensors provide an opportunity for individuals and communities to better understand their exposure to various air pollutants, both indoors and outdoors. These sensors are much smaller and lower in cost than traditional stationary air pollution monitors; for example, they may be small enough to carry in a hand or place on a tabletop and they may cost as little as a few hundred dollars. Sensors have been developed to measure several pollutants, including ozone, particulate matter, nitrogen dioxide, sulfur dioxide, volatile organic compounds and others.
