Air pollution is on the rise, and it is not just the governments that want to do something about it. Local organizations and industrialists are also asking for data to understand what is responsible for the damage of the air around them. Pollutant dispersion causes subtle yet fatal side effects on public health. Therefore, it becomes essential to understand their concentration levels and what they indicate. Ambient air quality monitoring systems measure different air pollutants like CO2, CO, NOx, SOx, O3, PM2.5 and, PM10, using sensors that help develop strategies to combat air pollution. But the accuracy of low-cost air quality monitoring systems is a primary requirement for effective mitigation.
