The aim of this project is to design and build a toxic gas leak detection station. To build this system, we adopted the following approach: - Mechanical design of the station. - Temperature control of the heating element. - Programming the system to carry out gas detection. - Validation of certain characteristics of a gas sensor. This project provided us with a valuable opportunity to put into practice the theoretical concepts we have studied throughout our training in electronics and automation. We hope that further work will build on this modest project to bring about possible improvements. For example, in addition to detection, we could introduce the ability to distinguish such a gas from a gas mixture, and we could reduce the size of the sensor.
