Smart in Sync Cylinder Reserving and LPG Gas Tracking System

Due to the rapid development of various fields, technology is developing rapidly, and it affects human life in all aspects. However, people should use these modern techniques to reduce our work loads. Currently, added a pre-booking system for LPG cylinders through online, which makes it difficult for illiterate people and those who are busy with schedules to pre-book LPG cylinders. Another major problem for users of LPG cylinders is that they are not able to know the level of LPG gas which leads to further delays in cylinder reserves, which is inconvenient for most companies. This paper proposes a system in which automatically performs the entire backup process of LPG cylinders without manual intervention. The system continuously monitors the weight of the cylinder using load cell and automatically sends a message to the authorized LPG agent when the minimum threshold is reached so that he can deliver the LPG cylinder on time. In addition to the automatic cylinder reserving part, there is also a user safety function that can continuously monitor the leakage of LPG using MQ-2 gas sensor and fire sensor also sense in case of fire is detected then it will activate the buzzer. Thus the user gets notified and thereby avoiding serious accidents that mainly cause casualties.
