GOOD AFTERNOON!
I would like to be informed what is the range of a purple air sensor installed externally, and what is the distance for installation in the external environment.
grateful,

Hello @Val
PurpleAir sensors measure air quality at a point rather than an area. You could find multiple suitable locations to place the sensor, but more sensors will be needed if you want more coverage for an area. More information can be found in our Sensor Coverage Area article.
