Development of a Mobile Liquified Petroleum (MLP) Gas Leakage Alert System with Multilingual Notifications

This project outlines the design and development of a Mobile Liquefied Petroleum (MLP) Gas Leakage Detection and Alert System with multilingual notifications for enhanced safety in an environment using Liquefied Petroleum Gas (LPG). The system continuously monitors LPG concentrations via an MQ-2 gas sensor and, upon detecting a leak, sends real-time alerts to users' mobile phones. Notifications are delivered in multiple languages, including English, Yoruba, Hausa, Igbo, and Berom(native language), making the system accessible to a diverse audience. The system features an ESP8266 microcontroller for gas level monitoring, with alerts displayed on an LCD and transmitted to a cloud platform for remote monitoring. It provides visual and audible warnings when gas levels exceed 550Parts Per Million (PPM), ensuring user safety. Key innovations include portability, low power consumption, and multilingual capability, ensuring quick and inclusive responses to gas leaks, with an average response time of 2.95 seconds. The system is cost-effective, user-friendly, and scalable for large-scale adoption in residential and industrial settings.
