Automated LPG Gas Detection and Booking System

In Indian household and commercial settings, LPG gas cylinders are extensively used for cooking and various other purposes. However, the highly flammable nature of LPG means that any leakage can result in dangerous explosions, posing significant risks to both life and property. Leakage can occur due to faulty valves, improper handling, or aging cylinders. This risk is heightened in both residential and commercial environments, where larger quantities of LPG are stored, increasing the potential hazard. Presently, there is no standard method for measuring the remaining gas in the cylinder, often leading to unexpected depletion and inconvenience. Moreover, many users are unaware that the expiry date of the gas cylinder is encoded directly on the cylinder. To tackle these issues, an advanced system using the ESP8266 microcontroller has been developed. This system includes gas sensors to detect leakage and load cells to measure the gas quantity in the cylinder. It employs Internet Protocol (IP) to alert users about gas leakage and cylinder weight, thereby enhancing safety and convenience in LPG usage. In the event of a leakage, a stepper motor mechanism stops the gas flow, preventing potential loss of life or property. The system also utilizes an ESP-32 camera module to identify the cylinder's expiry date, with OCR technology to read and communicate this information via Telegram messages. A Telegram bot updates users on the cylinder's status, including weight, gas level, leakage status, and expiry date. Additionally, when the gas level drops below a certain threshold, the system automatically books a new cylinder. This comprehensive solution ensures efficient management of LPG usage and enhances safety protocols.
