Abstract
Air pollution is a common cause of health risks and also a cause of
climate change, one of the most threatening problems to humans. This problem
results from the abundance of automobiles, industrial production, and
combustion of transportation and electricity generation petroleum products.
Therefore, forecasting air pollution is necessary. In this paper, a system is
proposed to monitor the level of air pollution by integrating the Internet of
Things(IoT) with Wireless Sensor Networks (WSN), where pollution levels are
observed in three areas in Baghdad using different types of sensors connected
with ESP32 (It is the name of the chip developed by Espressif Systems) to detect
Particulate Matter (PM2.5 and PM10), Nitrogen Oxides (NOx), Carbon
monoxide (CO) as well as temperature and humidity to monitor indoor and
outdoor air quality. Observed results are monitored by ThingSpeak, an open-
source IoT platform. Success has been achieved using the ESP32
microcontroller, as the project is low-cost and uncomplicated, and pollutant
measurement is accurate compared to the natural proportions of pollutants.
Data display is easy and it can be monitored easily. This encourages the
improvement of the model and its use in other monitoring systems.
