The Development of Air Quality Monitoring System using IoT and LPWAN

A long-term exposure to PM 2.5 may lead to health risks, cardiac arrhythmias and heart attacks, and respiratory effects such as plaque deposits in arteries that can eventually lead to cardiovascular abnormalities. This paper proposes the use of Internet of Things (IoT) and applications to monitor air pollution and weather using various sensors connecting through ESP32. We propose a wide-area system that monitors and detects the PM2.5. The conceptual model is clearly described and discussed in this paper with architecture and implementation framework. The Air Quality Monitoring System using LPWAN and IoT gave very precise results as a real-time graphical interface via mobile application.
