In this paper we present an air quality measurement
system that can be used to generate a map of the air quality in a
city. The system is made of stations that can be attached to buses
and taxis and gather data about air quality along the day as they
travel in the city. Each station has sensors to measure the
concentration of different gases, a position sensor (GPS) and a
GSM/GPRS communication module to transmit the data to a
central server. Each station is self-sufficient in terms of energy
through the use of a battery and solar panels. The data server
can be accessed through the internet using a browser and
presents the results in real time overlapped onto a Google map
of the city indicating, with different colors, the concentration of
each measured gas (CO, NO2, O3, SO2, and CO2).
