A Very Low Cost, Open, Wireless, Internet of Things (IoT) Air Quality Monitoring Platform

Since the recent epidemic rise of smog outbreaks across the country, it has become more crucial than ever to monitor and regulate the quality of air in the atmosphere. The established solutions so far are widely inaccessible for the general public and restricted specifically to organizational use due to high cost and less usability. In this paper we propose a standard solution based on Internet of Things (IoT) technology, which is a cost-effective alternative to traditional air quality monitoring systems. To realize this cost effectiveness, we have used NodeMCU system on chip which is a low cost, low energy, open, wireless LAN platform. Through the proposed solution, we demonstrate air quality monitoring by collecting data using temperature, humidity, carbon monoxide and nitrogen dioxide sensors and subsequently performed data analysis to infer the relationship of pollutant gases with weather parameters influencing the air quality. Through this research we support the concept of“Going Green” to sustain healthy, and cleaner environment for current and future generations.
