Abstract :
The measurement concentration range of SnO2 semiconductor sensors for toxic and flammable gases (TGS) was extended for use in air pollution monitoring. A real time autonomous system for air pollution monitoring (NH3, CO, R113 and R22 freons) using TGS sensors and an 80C552 INTEL microcontroller for data acquisition and management was tested. The air pollution concentrations measured in the industrial and residential areas of Bucharest fulfil the Romanian air pollution standards requirements as well as the US EPA ones. A simulator (SIMPA) for real time air pollution measurements was developed for the environment protection laboratories of scientific and technical universities
