Development of an Iot based air pollution and weather monitoring system with android application

Abstract

Development of an Iot based air pollution and weather monitoring system with android application Air pollution is one of the biggest environmental problems that affects the health, ecology, and environment and produces many severe impacts on human health. Vehicles are the biggest cause of air pollution in all large cities and the second main source of pollution is industry. Vehicle mass usage has led to a significant increase in atmospheric pollutants. This is the source of pollution in the human health. Other breathing issues such as asthma episodes and skin rashes have also occurred. The contaminants that pollute the air are unseen, leading to people's carelessness. Public recognition is therefore today's main requirement. The developments in the internet of things (IoT) allowed the quantity of harmful compounds in air particles to be monitored and air quality controlled. The goal is to use the MQ135 sensor to build a system that can detect the quantity of harmful particles in the air. A dedicated server can be used to manage air quality through the internet. When the amount of toxic particles in the air, such as CO (Carbon Monoxide) an exhaus fant will automatically switched on and remove harmful air. Air quality in PPM (Parts Per million) is displayed on the web server when the toxicity in the air crosses the threshold value and automatically air purifier gets switched on, and it detoxifies the air.This device also able to detect LPG gas by the help of MQ-2 sensore and this device also detect temperature and humidity by the help of DHT-22 sensor . In this device we’ve added a dummy exhaust fan that will turn on automatically when the air quality cross the limit of moderate air quality. The device may be put anywhere, and some external devices can be activated if pollution passes the safe area such as the Android application can send a notification to all users. Our effort is designed to provide indoor air quality monitoring and analysis with a low cost budget system in real time. Our project work is important for all general users who can easily achieve the level of indoor air quality and can thoroughly monitor indoor air quality [1]
