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.

Workshop contamination can lead to changes in the characteristics of the air.Welding process for example inside the workshop will generate different pollutants just likefume and gases. These gases may threat the environment. Also the direct exposure of thesegases by people inside the workshop may be considered as a risk on their health. For allreasons mentioned above air pollution monitoring system is important issue to decreasethe risk of low level of health. This paper introduces the implementation of wireless sensornetwork to monitor a workshop air pollution.The proposed system prototype contains a set of gas sensors (CO, H2, NH3, Butane,Propane, Ethanol and NO2) which are deployed on stack and infrastructure of Wirelesssensor Network. These sensors are calibrated using appropriate calibration technologies.They are controlled by ARDUINO based microcontroller. Also there is the main serverwhich Installed on raspberry pi 3 and contains the main database of the system whichsupports real time management strategies by using the web interface to monitor the airpollution in form of numbers and charts.Sensors which controlled by ARDUINO platform are connected to the server using thewireless technology (Wi-Fi) and the communication is done by using Message QueuingTelemetry Transport protocol (MQTT).When the level of Carbon Monoxide gas is abovethe threshold the system will send an alert email to the department of the civil defense.The system is checked and tested in the training workshops of University of Technology tomeasure the levels of harmful gases which may harm the people in the workshops.
