Development of a Gas Leakage Detection and Alert System for Enhanced Safety

Abstract This study aimed to design and develop a gas leakage detection and alert system to enhance safety in residential, industrial, and transportation settings. The system was developed using an MQ-5 gas sensor, Arduino Nano microcontroller, LED indicators, GSM module, and a 16x2 LCD display. Simulated gas leaks were introduced to test the system's performance under various environmental conditions, including humidity and temperature variations. The system demonstrated consistent performance in detecting hazardous gases like LPG and methane, triggering alerts within 2-5 seconds of the gas detection. It maintained accuracy across various environmental conditions, including humidity levels ranging from 30% to 90% and temperatures from 0°C to 37°C at Effurun region of Delta State. The system showed high robustness and adaptability to different operating conditions without compromising detection accuracy or alert response time. It seamlessly switched to battery backup during power outages, ensuring continuous operation for up to 6 hours. The developed system has significant implications for enhancing safety in various settings, including residential, industrial, and transportation. Its ability to detect hazardous gases and trigger alerts in real-time can help prevent accidents and minimize risks. The system's robustness and adaptability make it a reliable solution for gas leakage detection and alerting.
