Gas Detection System using Arduino

Gas leaks are among the leading causes of industrial and residential accidents, resulting in fires, explosions, and significant health hazards. Early detection of gas leaks is crucial in preventing such incidents and ensuring the safety of individuals and property. This paper discusses the development of a gas leakage detection system utilizing an MQ-5 gas sensor, Arduino UNO Microcontroller, and a buzzer. The proposed system operates in real-time to detect hazardous gases like LPG and methane and provides audible alerts upon detection. The design prioritizes affordability, ease of use, and reliability, making it accessible for widespread adoption in homes, workplaces, and industries. This innovative solution meets the growing demand for low-cost safety devices and contributes to enhanced safety standards globally.This paper presents the development of a gas leakage detection system that integrates an MQ-5 gas sensor, Arduino UNO Microcontroller, LCD display, and buzzer to enhance safety in homes and industries. The system continuously monitors the concentration of hazardous gases like LPG and methane. When dangerous levels are detected, the system triggers an audible alert through the buzzer and displays the gas concentration level on the LCD screen. This real-time monitoring system is designed to be cost-effective, reliable, and easy to use, making it suitable for diverse applications, including residential and industrial environments.
