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.
