|Workshop contamination can lead to changes in the characteristics of the air.
Welding process for example inside the workshop will generate different pollutants just like
fume and gases. These gases may threat the environment. Also the direct exposure of these
gases by people inside the workshop may be considered as a risk on their health. For all
reasons mentioned above air pollution monitoring system is important issue to decrease
the risk of low level of health. This paper introduces the implementation of wireless sensor
network 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 Wireless
sensor Network. These sensors are calibrated using appropriate calibration technologies.
They are controlled by ARDUINO based microcontroller. Also there is the main server
which Installed on raspberry pi 3 and contains the main database of the system which
supports real time management strategies by using the web interface to monitor the air
pollution in form of numbers and charts.
Sensors which controlled by ARDUINO platform are connected to the server using the
wireless technology (Wi-Fi) and the communication is done by using Message Queuing
Telemetry Transport protocol (MQTT).When the level of Carbon Monoxide gas is above
the 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 to
measure the levels of harmful gases which may harm the people in the workshops.
