Liquefied Petroleum Gas (LPG) is one of the most commonly used fuels for domestic cooking, commercial kitchens, and small industrial applications due to its high energy efficiency, easy storage, and convenient transportation. Despite its advantages, LPG is highly flammable and can pose serious safety risks if not handled properly. Gas leakage, improper monitoring of gas levels, and accidental fires are some of the major concerns associated with LPG usage. Many accidents occur due to undetected gas leaks or delayed response when the gas level becomes critically low. Therefore, there is a need for an intelligent system that can continuously monitor LPG cylinder levels and detect unsafe conditions to prevent potential hazards.
This paper presents the design and implementation of a Smart LPG Gas Level Monitoring and Safety System based on the Internet of Things (IoT). The main objective of the proposed system is to improve safety, provide real-time monitoring of LPG cylinder levels, and alert users about potential hazards. The system uses a load cell sensor to continuously measure the weight of the LPG cylinder. By analyzing the weight of the cylinder, the system can estimate the remaining amount of LPG available. This allows users to monitor gas consumption and receive early notifications when the gas level becomes low, enabling timely replacement or refilling of the cylinder.
