Smart IoT Based Gas Leakage Detection and Auto Shut-Off System

Abstract

Gas leakage poses a significant threat in residential and industrial environments, often leading to hazardous situations like fires and explosions. This paper presents a Smart IoT-based Gas Leakage Detection and Auto Shut-off System that enhances safety by integrating real-time monitoring with an automated response mechanism. The system detects gas leaks using an MQ-6 sensor and promptly shuts off the gas supply through a servo motor-based valve control. Additionally, an alert notification is sent to users via an LCD display and buzzer to ensure immediate awareness. This paper discusses the half-implemented version of the system, focusing on gas detection and auto shut-off functionalities. The proposed system improves upon existing gas detection techniques by offering a cost-effective, highly responsive, and automated approach to preventing gas-related accidents.
