Short summary
The PurpleAir PA-II is a low-cost sensor for monitoring changes in the concentrations of particulate matter of various sizes. This study examined the behaviour of multiple PA-II units in four locations in the USA under atmospheric conditions when exposed to a variety of pollutants and different PM2.5 concentrations. The PA-II unit is a promising tool for measuring PM2.5 concentrations and identifying relative concentration changes, as long as the
PA-II PM2.5 values can be corrected.
The PurpleAir PA-II is a low-cost sensor for monitoring changes in the concentrations of...
