Air pollution is the initiation into the environment of chemicals, particulates, or organic elements that create distress, sickness, or death to humans. To examine how contaminated the air is an Air Quality Index (AQI) is in practice. This index corresponds to the people how contaminated the air is currently. As the AQI advances, the well-being of the people declines. The only way to reduce the AQI is to utilize the advanced technology.
