IoT-Based Gas Leakage Detection and Monitoring System

Abstract

Gas explosions in Nigeria have contributed significantly to loss of lives and properties, with a rising trend over the past four years indicating a critical need for preventive solutions. This paper presents the development of an Internet of Things (IoT)-based system for the early detection and monitoring of Liquefied Petroleum Gas (LPG) leakages, aimed at reducing fire-related incidents in gas filling stations. The system is designed using an integrated circuit that incorporates gas sensors, an LCD display, a buzzer, and other selected materials, all connected to an ATmega328P microcontroller. Upon detection of gas leakage, real-time data is transmitted via GSM to a web-based application that handles data logging, analysis, and geographical tracking of gas stations. The web platform also serves as a tool for providing safety information and alerts to relevant stakeholders. Experimental results and performance evaluations indicate that the proposed system is effective in detecting gas leakages early, thereby enabling timely intervention and significantly reducing the risks of explosion. The system’s deployment offers substantial benefits in terms of safety, economic loss prevention, and improved emergency response strategies within Nigeria’s LPG distribution sector.
