Development of a Low-Cost Gas Leakage Detection System With Auditory and Visual Alerts

Abstract

<title>Abstract</title> Household gas leakage stands as a significant contributor to domestic accidents in society. This study focuses on addressing this issue by introducing an affordable and easily accessible device capable of delivering both audio and visual alerts in local dialects based on the language spoken within the household. The system incorporated a 5v buzzer for audio alerts and an LCD for visual alerts, forming the core components of this innovative solution. The coding, executed through Arduino IDE, orchestrated the interaction between the MQ2 sensor and the Arduino Nano, activating auditory alerts via the buzzer and visual alerts through the LCD. The findings highlighted system's efficacy as an affordable safety device for homes, addressing potential dangers associated with gas leaks. The utilization of commonly available components enhanced its cost-effectiveness, ensuring accessibility for households with budget constraints. Furthermore, the system's adaptability was showcased through the programmable LCD, allowing users to display messages in local dialects based on household language preferences. This feature enhanced user experience, making the system more inclusive and aligned with the diverse needs of different households.
