Automatic Industrial Gas Leakage Detection and Control System

This project's primary goal is to develop a successful functioning prototype that can detect the existence of gas leakage, which in this case is liquefied petroleum gas (LPG) and control the gas to prevent leaks in great amounts. The prototype should perform immediate data transfer and warning in addition to detection and control. This can be done by implementing an alerting system, such as an alarm via a buzzer, an application via a Wi-Fi module, and SMS via a GSM module. Here, the alerting system is in place to inform nearby residents and industry workers about the leakage. Once a leak has been discovered, the first step is to pinpoint its precise location. This can be done in two different ways. The first way is to check the pressure using a barometric pressure sensor in each region, if there is a difference between the pressure in one region and the previous which means a leak of gas has occurred; the higher the pressure drop, the bigger the leak. The second approach involves using an appropriate gas sensor, in this case MQ-6, to directly detect the gas concentration that is leaking. This is accomplished by comparing the error between the actual value and the predetermined value of the sensors. Here, we are combining both the approaches to increase redundancy. When this condition is met, an alert is triggered, and valves at the location of the gas leak are controlled using an Arduino Mega Controller. Further repair action will be performed at the damaged pipe line. This results in a shorter response time for damage restoration. As a conclusion, this project has offered students the chance to incorporate theories into solving issues relevant to the engineering scope of work
