Short summary
Air pollution sensors are quickly proliferating for use in a wide variety of applications, with a low price point that supports use in high-density networks, citizen science, and individual consumer use. We evaluated the performance of particulate matter, ozone, and nitrogen dioxide sensors in Denver, Colorado, over a period of seven months. We found that these sensors could vary greatly in their performance, but some were able to replicate trends measured by traditional instruments.
