DEVELOPMENT OF AIR QUALITY MONITORING DEVICE (AQMD) WITH INTERNET OF THINGS (IOT) APPLICATION

Abstract

A prototype Air Quality Monitoring Device (AQMD) has been developed to monitor the concentrations of major air pollutant gases. The system uses inexpensive air-quality monitoring nodes that incorporate a semiconductor gas sensor and a wireless module. This system uses semiconductor sensors to determine the concentrations of several gases, including PM 2.5, CO, SO2, and NO2. The sensors can collect data on a variety of environmental variables and transmit it to the Arduino Mega 3560 R3 serving as a base station. Additionally, a temperature and humidity sensor was added to the prototype. Sensor data is visualised using the Blynk application on a mobile device. The intended study's defining characteristic is the establishment of a low-cost infrastructure for data collecting. As a result, it is believed that this integrated strategy might open the way for other initiative-based approaches to resolving issues, particularly in the industrial sector.
