Economically Air Quality Monitoring System Using NodeMCU

Abstract

The aim of this research is to examine the monitoring systems for air quality, their supporting technologies and protocols. Due to its notable impact on society health and the global economy, the primary concern is air quality, particularly in modern cities. The importance of the data on air quality makes the very reliable real-time monitoring systems important. The limited data access, high cost and non-scalability of the traditional air monitoring system enforces researchers to build potential air quality monitoring systems using emerging technologies such as NodeMCU, Internet of Things (IoT) and low-cost environmental sensors. In addition, the present study discussed the challenges, foundations and methods of developing a framework for tracking air pollution in real time using IoT technologies. Finally, the analysis addressed the limitations of current works and outlined the targets to be met in future air monitoring systems in order to make them more reliable and practical.
