A new feature from “Google Maps” that connects you to places with fresh air

The American “Google Maps” application has introduced a new feature that indicates its users to places with fresh air
The new feature is useful when planning an upcoming trip, cycling at the most appropriate time, or planning to escape smog and smoke, according to The Verge.
Google Maps displays the air quality index live across its network, using government data collected from agencies such as the Environmental Protection Agency (EPA) in America to show how healthy the air is in general.

The application also relies in its information provided to its users from data collected from the network of “PurpleAir” sensors, to report on severe local conditions at street level.
Relatively inexpensive, “PurpleAir” sensors measure particles using laser particle counters, by shining a laser through the air to reveal the particles in it, and the detector picks up on those reflections.
Clicking on the Air Quality Index readings in Google Maps provides more information about the health impact of air quality in an area, the time and source of the last reading, and links to learn more.
