IoT technology allows users to measure the quality of the air by controlling several parameters.
Air pollution means the amount of Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), and Carbon Monoxide (CO) in the air exceeds the criteria set by the World Health Organization (WHO).
The Air Quality Index measures the quality of air. It shows the amount and types of gases dissolved in the air. The air quality index is composed of 8 pollutants (PM10, PM2.5, NO2, SO2, CO, O3, NH3, and Pb).
There are 6 categories of air in the air quality index. The categories define the quality of the air. They are as follows; good, satisfactory, moderate, poor, very poor, and severe.
The WHO Air quality guidelines offer global guidance on thresholds and limits for key air pollutants that pose health risks. As an example, the Guidelines indicate that by reducing particulate matter (PM10) pollution from 70 to 20 micrograms per cubic meter (μg/m), we can cut air pollution-related deaths by around 15%.
