Air Quality Monitoring System Using LoRaWAN and Helium Network

Abstract

The aim of the project "Air Quality Monitoring” using low-cost sensor is to measure the air quality index after measuring the concentration of air pollutants in a particular area and display the results on mobile application. The proposed system architecture integrates these sensors which are capable of measuring key air quality parameters, including particulate matter (PM), carbon monoxide (CO), and nitrogen dioxide (NO2). These sensors wirelessly transmit the collected data to a LoRaWAN gateway, which serves as a relay for the Helium network. The Helium network, functioning as a decentralized infrastructure, ensures secure data transmission and storage. The main feature of the project is to develop a mobile application that displays the air quality index derived from the measured pollutant concentrations using sensors. The application serves as user-friendly interface, allowing users to access real-time air quality information and make decisions regarding their health and well-being
