The presence of dust in homes, offices, and other human environments are unavoidable. In fact, according to the Environmental
Protection Agency, indoor air can be 2 to 5 times more polluted than outdoor air. This airborne pollution contributes to minor
annoyances such as itchy eyes, sneezing, and headaches to human beings. Worst still, it can be a major contributing factor to severe
allergies & life-threatening asthma. To solve this problem, a working air purification system will address this issue. I would like to
leverage the advantages of sensors and to make the air purifier smarter. Instead of the conventional way that turning on the air
purifier whole day, but with the use of "microcontroller” and "sensor” to operate only if the presence of dust reach certain level of
awareness, this could save a lot of electricity and also keep the room, apartment, not only clean the air pollutants in the room but
also monitors the quality of air been purified at the particular instant of time .
