Real-time Gas Leak Detection System

Abstract

The “Real-time Gas Leak Detection System” is a safety-critical project designed to monitor and detect hazardous gas leaks in real time, ensuring prompt alerts and preventing potential disasters. The system integrates gas sensors, microcontrollers, and communication modules to continuously monitor the environment for the presence of harmful gases. Upon detecting a leak, the system triggers alarms and sends notifications to designated personnel via a mobile application or SMS. The project aims to enhance safety in industrial, residential, and commercial environments by providing an efficient, reliable, and cost-effective solution for gas leak detection.

Existing System

The existing gas leak detection systems predominantly rely on manual inspections or outdated detection mechanisms, which often lead to delayed responses in the event of a gas leak. Many of these systems are not capable of providing real-time alerts or remote monitoring, which limits their effectiveness in preventing accidents. Additionally, some existing systems may be limited to detecting only specific types of gases and lack integration with modern communication technologies for alerting stakeholders. This leads to increased risk, especially in environments where a swift response is critical.

Proposed System

The proposed Real-time Gas Leak Detection System aims to address the limitations of existing systems by incorporating advanced gas sensors capable of detecting multiple types of hazardous gases. The system will be equipped with a microcontroller to process sensor data in real-time and a communication module to send immediate alerts to a central monitoring station and mobile devices. The system will also include a user-friendly mobile application for remote monitoring, providing real-time updates and historical data. By integrating IoT technology, the proposed system will enhance safety and provide a proactive approach to gas leak detection.
