Air quality measurement gets personal with advanced PM2.5 and VOC sensor technologies

In both indoor and outdoor environments, poor air quality can greatly impact our health and well-being. Two important indicators for air pollution measurement are small particulate matters (PM) of 2.5 microns or less (PM2.5) and volatile organic compounds (VOCs). Official air quality monitoring stations provide only consolidated or averaged data for the outdoor environment without the corresponding indoor air data. They do not generate personalized information. A portable air quality measuring device or dosimeter for air pollution measurement – for example, in our smartphones or wearables – could solve this problem. This article provides insights into new PM2.5 and VOC sensing technologies that enable personal air quality monitoring to improve people’s health and well-being.
