Public Air Quality Indicator

The aim of the Public Air Quality Indicator project is to make existing information on air quality and pollution levels accessible. The indicator gives information specific to the location in which it is placed in the city and is updated 4 times a day.

A similar system controls a window opener on the city hall. Depending on the current pollution level, the window will close (warning) or open (pollution below average) enabling the public to read the indicator from the street.
