IoT-based Air Monitoring System

Abstract

The contamination of an indoor or outdoor environment by any chemical, physical, or biological substance that affects the inherent features of the atmosphere is referred to as air pollution. The most common causes of air pollution include fires in forests, automobiles with internal combustion engines, factories, and other types of industrial operations. Pollution in the air is quite close to the top of the list, which makes it one of the most important contributing factors to bad health all over the world. Not only does exposure to air pollution shave years off of people's lives, but it also has a significant impact on the quality of their lives while they are still alive. world health organisation research indicates that almost all of the world's population, or 99%, breathes air that is considered to be unhealthy since it exceeds the guidelines set by WHO and contains high amounts of pollutants. The countries with the lowest and intermediate incomes experience the highest levels of pollution exposure. The climate and ecosystems of the world are intimately connected to the quality of the air that we breathe. PPM's air quality monitored globally by an air pollution monitoring system that makes use of the internet of things (IoT). The proposed system identifies any gas leakage and record the data collected on online servers for later use. In the event that the air quality falls below a predetermined limit, the proposed system will sound an alarm using MQ135 and MQ6 sensors. These sensors are able to identify dangerous chemicals that are present in the atmosphere and determine the precise concentration of those gases in real time. In addition, the systems have a gas sensor, which is able to identify the presence of any gas leakage that may have occurred.
