A graduate student from the Department of Computer Engineering at the University of Technology (Hasnaa H. AbdulKareem) has been awarded a Master of Science degree in “Smart Monitoring System Design for Air Pollution Avoidance Based on Wireless Sensor Network”, on 13 November, 2019 at the conference hall of the Computer Engineering Department.

This thesis presents air pollution monitoring system based on wireless sensor network. The proposed system contains two different sensor nodes connected to the Raspberry Pi main server. These two sensor nodes contain air gases sensors to detect harmful gases in the air and monitored by microcontrollers.

Readings of sensors are stored on the main database system of raspberry pi. MySQL database system is used because it is expandable, moreover web service is implemented to allow real time monitoring and provide user interfacing. Also, MQTT protocol was implemented to send and receive messages between sensor nodes and the main server.

The results of system are compared to the results of microtector II gas detector device which is very efficient and precise. The results of both microtector and the proposed system are the same. The results of the proposed system prototype verified the expected aims, namely: air pollution system monitoring and avoidance.

The discussion committee consisted of four members, Prof. Dr. Ahmed S. Abdul-Amir from the University of Technology – Iraq, Computer Engineering Department as Chairman, Asst. Prof. Dr. Zainab T. Al-Essa from the Baghdad University, College of Engineering, Electrical Engineering Department as a member, Dr. Azhar A. Kamel from the Higher Education and Scientific Research Ministry, Research and Development Department as a member, and Asst. Prof. Dr. Hassan J. Hassan from the University of Technology – Iraq, Computer Engineering Department as a member and supervisor.
