Air contamination is one of0the largest ecological0as well0as community health trouble in the world. It effects person health climate and0ecology Due to the release of0toxic gases by industries, increased0concentration of0harmful gases and0particulate0matter in the atmosphereand0vehicular emissions air0is getting polluted0Particulate matter0is one of0the most important0parameters having the s ignificant0contribution to the increasing air pollution Due to which measurement and analysisof0real-time0is quality parameters becomes important so that proper conclusions may be0taken inside a sensible base. Here it gives the0survey of0various methods used0so far to detect air quality along with overview of the project which results into real-time and alone air quality calculator parameters like temperature, pressure, relative moisture, PM 2.5, PM10,Co2.
