Design And Fabrication Of A Microcontroller Based Liquefied Petroleum Gas Leakage Detection With Gsm Alert Monitoring System

ABSTRACT

Liquefied Petroleum Gas (LPG) is a group of flammable hydrocarbon gases that are

liquefied through pressurization and commonly used as fuel. This project aims to design and

implement a micro-controller based Liquefied Petroleum Gas (LPG) gas monitoring & leakage

detection system with GSM alert system. Design and implementation of gas detection system as

well as SMS alert systems were done to achieve the project aim.

Gas leaks can cause major incidents resulting in both human injuries and financial losses.

To avoid such situations, a considerable amount of effort has been devoted to the development of

reliable techniques for detecting gas leakage. Various literatures were reviewed and compared,

and conclusions were drawn chapter two gives the detailed accounting of the literatures as well

as the review of fundamental theories about the project.

Chapter three shows the design steps taken to actualize the project. The system is built

around three sensors; gas sensor, load cell and temperature sensor. These sensors are interfaced

together to an embedded system. Software simulation of the design was done using Proteus

professional software and the design was actualized on a printed circuit board.

The design was tested by deliberately exposing it to gas leakage, the alarm system of the

design goes off and it sends a SMS text to the.user to notify about a potential threat.

The goal of this project was achieved by fabricating and design a device that detect Gas leakages

effectively using a gas sensor and alert people and also the designed system is capable of

notifying the user about the level of the gas in the cylinder through the weight sensor.

Improvements can be made on the system to make it a more efficient detector system by

using Internet of Things (IOT) instead of SMS alert notification for the proper monitoring and

control of the system. To ensure uninterruptible power supply, solar power can be incorporated

into the design. Another improvement can be made to ensure it can also be powered using a battery as ac power cannot be stored.
