- The air quality of a given area can be utilized as one of the key determinants of the pollution index, as well as how well the city's industry and population are controlled. With the rise of industrialisation, monitoring urban air quality has become a persistent issue. All around the world, air pollution has remained a severe concern for the public and the government. Air pollution has a notable impact on both the environment and human health, resulting in acid rain, global warming, heart disease, and skin cancer. A metric called AQI is calculated by evaluating the concentration of various PM, such as PM2.5 and PM10, present in the air to estimate the severity of air pollution. Our goal for this project is to design and construct a real-time AQI monitoring system that can be easily controlled and manufactured at a low cost, as well as an air purifier that continuously removes tiny particles (PM2.5 and PM10) from the air, decreasing the harmful impacts of pollution.
