Air Quality Monitoring System (AQMS) which incorporates Internet of Things (IoT) and cloud computing. AQMS utilizes solar panel and battery pack for independent and autonomous operation, thus, making it self-powered and sustainable. AQMS is based on AVR Microcontroller (Atmega32) and GSM modem (Sim900) for connectivity with the cloud application. The design is made low cost and scalable so that around 50nos. of such systems can be installed on roundabouts of market places, residential and industrial areas. The AQMS monitors the air quality with the help of a miniature suction pump (5volt DC) which establishes a controlled and constant stream of air-flow through a manifold that encapsulates electromechanical sensors, thus measuring the concentration of O2, CO, CO2, SO / SO2 (SOx), NO/ NO2 (NOx), Hydrocarbon (CxHx), temperature, humidity and noise. By default, the air sampling is carried out once in an hour which may be changed depending on the change in air quality, i.e. making it adoptive for energy conservation and extending the sensor's life. The data collected at the cloud application will be processed using data analytics and Artificial Intelligence (AI) for getting insights of data (data mining) regarding the potential locations where the emissions are critical and disastrous for environmental, thus, leading to prevent any mishap. The design is mapped over a metropolitan city of Pakistan, i.e. Karachi, thus initiating the transformation of Karachi to a smart city.
