IoT based Indoor Air Quality Monitoring System

The Internet of Things has been proving its potential to solve problems where presence of information can contribute big to a solution or become the solution itself. A whole range of connected things, talking to each other can communicate processed information to people that would help them in arriving at meaningful conclusions about abstract, yet important factors. One such factor is air and its quality. In a population dense world and looking at the trends in the number of casualities due to unclean air it is highly important that people are informed of the quality of air that they breathe. Indoor air quality is a very important factor to be judged and analysed and the need for an effective solution to do so is inevitable. With air purifiers being able to clean the air indoors, there is no room for users to check the consistency of such a process and no provision to study the long time behaviour of air they get to breathe. In this paper, a solution that would make users study the air around them both in real time and over a period of time would be presented. A variety of pollutant concentrations would be measured and informed to users, alerting users thereby of some of the most harmful pollutant concentrations.
