Importance of IoT in Environment Monitoring: A Comparative Study of COVID19 Impacts on Air

Internet Of Things technologies are able to monitor and give information about the environmental conditions. Researchers can easily track the different parameters, affecting the environment and can control the situation. Environment is getting polluted day by day because of many reasons. Air pollution, water pollution and radiation pollution are major challenges faced by the environment. Contamination in a real environment can be found and measured by IOT tools and techniques. In this paper we took 7 cities of highly polluted city “Delhi” and analysed their AQI before COVID 19 pandemic i.e. 2018 and the lockdown duration of 2019 and 2020. We have clearly seen that during lockdown AQI has been improved, only because of less vehicles. We state here the importance of IoT based wireless sensor devices in environment monitoring which can alarm us before getting too late. Vehicle emission is a very important factor, which badly affects the air. IOT can contribute in preparing guidelines for a country to minimize the pollution. Suitable monitoring is necessary for sustainable growth for any country. This paper also enlightens the impacts of Covid19 on the environment i.e. air. This study will help in understanding that if we control vehicle emission then surely it will improve the Air Quality Index.
