Design and Execution of an Internet of Things Based Air Pollution Monitoring Device

Increasing urbanization and industrialization, deforestation, and other human activities have caused high-level contamination of the air that we breathe. Breathing unhealthy air deteriorates human health and leads to serious and long-standing diseases such as asthma, congestive heart failure, respiratory infection, etc. As a result, monitoring and estimating the levels of various air defilements such as PM

, and Ozone is required for raising citizen awareness about the quality of the air they breathe. This paper presents an IoT-enabled smart device named AirHealth which provides geographical-based pollution insights by detecting and measuring the levels of different air pollutants, calculating the air quality index at the installed location along with temperature & humidity levels. The prototype design consists of a microcontroller assembled with electrochemical sensors, GPS, a GSM module, and a RTC clock. The data collected can be remotely monitored on the website & ThingSpeak application on smartphones allowing people to know about the quality of the air they breathe and precautions they can take to refrain themselves from serious diseases.
