Abstract

This paper presents a low-cost, efficient LPG leakage detection system designed for household use. It uses an MQ-6 gas sensor and a microcontroller to determine air concentrations. Upon detection, an audible buzzer and visual indicators alert occupants. The system also includes an automatic shut-off mechanism and global system for mobile modules for remote notification. Powered by a reliable source, it has rapid response times, high sensitivity, and cost-effectiveness. When gas concentrations surpass a safe ceiling, the microcontroller triggers a relay to cut off the power supply, preventing sparks and explosions. Additionally, a buzzer alerts people nearby with a loud sound, while a GSM module sends emergency messages to registered contacts. The system’s main components include the microcontroller, gas sensor, relay, buzzer, and GSM module. The outcome is cost-effective, energy-efficient, and appropriate for both homes and industrial settings. By detecting leaks early and automatically shutting off power, it enhances safety and helps prevent accidents, ultimately saving lives.
