Abstract—A change in air quality that may be identified by measurements of the chemical, biological, or physical pollutants in the air is known as air pollution. Air pollution thus refers to the presence of contaminants or the abnormal increase in the concentration of particular atmospheric elements. It can be divided into two categories: invisible and visible air pollution.Air quality monitoring is a big task in urban areas., Especially in the developing countries like India people suffers from various health hazards like asthma,lung cancer and some of the respiratory problems like emphysema.Additionally, long-term exposure to air pollution can harm a person's nerves, brain, kidneys, liver, and other organs. Some scientists think that birth abnormalities are caused by air pollution.This paper presents an Internet of Things (IOT) enabled air quality monitoring system in nature and analyses real-time ambient data measuring levels of PM, methane, butane, alcohol, LPG gas, carbon monoxide, smoke, and nitric oxide. The system can monitor contamination of air quality in the local area and alerts the people around the contamination area with the buzzer sound that is installed in the device built into the system. The system technology is so user-friendly and simple to operate that it can be implemented in homes, businesses, and even entire cities.
