Android Based Gas Booking System and Leakage Detection Using IOT

Liquefied Petroleum Gas (LPG) is widely used in households and industries, but gas leakage and the unavailability of gas cylinders pose significant safety and convenience challenges. This project presents an IoT-based Gas Leakage Detection and Automatic Gas Booking System that enhances safety and automation. The system integrates Arduino Uno and ESP32 microcontrollers to monitor gas levels and detect leakage in real-time. A Load Cell is employed to measure the weight of the gas cylinder, ensuring continuous monitoring of gas consumption. When the weight of the cylinder drops below a predefined threshold, the system utilizes the GSM module to automatically book a new gas cylinder by sending an SMS notification to the authorized distributor. For safety measures, an MQ-05 Gas Sensor is incorporated to detect any gas leakage. Upon detecting leakage, the system promptly sends an SMS alert to an authorized mobile number, allowing immediate action to prevent hazards. The proposed system enhances safety, reduces manual intervention, and ensures the timely availability of gas cylinders. It also provides a cost-effective and scalable solution for households and industries. By leveraging IoT-based automation, the system significantly improves efficiency in gas booking and safety management, contributing to smart home and industrial applications.
