A distributed measurement system for the estimation of air quality

Currently, one of the most serious environmental problems on the planet is air pollution by fine dust, including Particulate Matter with an aerodynamic diameter of about 10 µm (PM10) and 2.5 µm (PM2.5). The high concentration of these components, particularly in urban and industrial areas, leads to a worrying incidence of respiratory diseases. In fact, these dusts, which can be compared to a slow and silent killer, are so small that they can be inhaled and gradually accumulated in the respiratory system, which, according to the World Health Organization (WHO), has been the cause of death of 12 million people in the past five years [1].
