Design and Development of Air Quality Monitoring System for Higher Education Institute using MQ-2 and MQ-8 with WSN and IoT

Abstract

Most schools, universities, and educational institutions are close to significant intersections and the city center. Therefore, it is crucial to understand the air quality levels in these institutions' vicinity. More than 25% of a student's day is spent on educational institutes premises. The most vulnerable population is in the greatest danger due to the poor air quality levels on campuses and in schools. Young children's lungs are especially susceptible to air pollution, according to the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF). While the immune system is still developing, childhood exposure can lead to lung cancer, asthma, and other long term respiratory health problems. This air monitoring is necessary in and around the school and university facilities as a result. This paper discusses the wireless sensor network (WSN) and internet of things (IoT)-based air quality monitoring system that uses MQ2 and MQ8 sensors. The goal of this system is to monitor the air quality in the institutions. MQ2 and MQ8 sensors were employed in the study to measure the concentration of gases in the air, including LPG, propane, methane, hydrogen, alcohol, smoke, and carbon monoxide. Thingspeak is an IoT cloud platform that houses all acquired data. Data is shown on the website following analysis. This technique aids in better decision-making and reduces the likelihood that pupils may experience pollution-related health problems.
