How to Build a Particulate Matter Detector for Air Quality ...

Mar 28, 2018 · For air quality, particle sizes are frequently grouped into two categories: those smaller than 2.5 µm and those smaller than 10.0 µm. In this regard, the USEPA sets standards for exposure to such “particle pollution”. The standards are expressed as a function of particle concentration and exposure duration (e.g., 24 hour and annual).
