Taking into account that air pollution is one of the most debated issues in the world, this paper proposed a flexible solution for the development a chemical sensor networking able to collect and transmit data for the atmospheric pollutants. The System_Acqusition_Monitoring_Warning-SAMW is composed by a large palette of sensors integrated within Digital Acquisition and Processing System-DAQ, to convert chemical signal in electrical signals easily to be transmitted to a PC server. The air quality monitoring data from different points of map is centralized by a software application. The new proposed software application allows reading, acquisition and monitoring of analogue signals, voltages and currents correlated with the concentrations of main air pollutants. The platform also enables optical and acoustic signalling when the pollutants exceed admissible limits. The application allows both visualization and graphic representation of acquired signals in real time on the computer where is connected the acquisition board. Continuously acquired data are automatically stored in a database to be sent via Internet to a central server for analysis, processing, interpretation and warning. Following these warning, the human operator can take fairly and expeditiously decisions on emerged technological risks. The reported results represent the first map of the cropped pollutants from the atmospheric environment in the Romanian area.
