Abstract
Wireless sensor network (WSN) enhanced the process of monitoring many environmental phenomena such as the air pollution monitoring issue in proposed this paper. In this paper, a WSN based microcontroller equipped with gas sensors have been actively used for air quality monitoring. The design included several units mainly. Arduino Microcontroller, MQ-2 Gas Sensors, and the current regulator circuit. Based on the normal gas levels of the clean air, the obtained results indicate that there is a big difference in the gas levels of both gases (LPG and CO) which obtained from the several tests and circuit runs. However, the acquired results for the air quality control inside the KFU buildings show no risky situation to be considered for further actions. This work will apply the electrical engineering techniques as well as environmental engineering knowledge by using wireless sensor networks to measure Air Quality Parameters such as Carbon Monoxide (CO) and Liquid Petroleum Gas (LPG).
