A low cost air quality sensor network providing real time measurement of air quality on a public map. Useful to citizen scientists or air quality professionals alike, PurpleAir sensors are easy to install, requiring only a power outlet and WiFi.
With the LRAPA conversion, the PurpleAir sensors are reasonably accurate and correlate much better to the AirNow values. However, there are two reasons for the discrepancies between the readings. The first is that the AirNow numbers are the average reading over the last hour, while the default on PurpleAir averages over the last 10 minutes.
The purple air takes measurements based on how much interference is in the air, but the scale they use is based on how many solids are in the area. Relatively small and light contaminants like smoke are not as damaging as they would first seem. The LRAPA scale compensates for this. level 1. photograft.

Thanks again to Brett Singer for info on LRAPA. The laser sensors used by Purple Air rely on a hard-coded constant that represents the average density of the particles it is detecting. Because wood smoke particles are less dense (1.5 g/cm³) than typical PM 2.5 particles, the resulting AQI values are too high.
