Liquefied Petroleum Gas (LPG) is extensively used in domestic households, commercial kitchens, and small-scale industries because of its efficiency and cleanliness. However, gas leakage and improper monitoring of gas levels often lead to serious safety hazards and inconvenience. This paper presents an IoT-based gas level detection and auto booking system that continuously monitors gas leakage and remaining gas quantity in an LPG cylinder. The system uses gas sensors to detect leakage and a load cell to measure the cylinder’s weight, enabling accurate estimation of gas levels. A microcontroller processes the sensor data and transmits it to a cloud platform using wireless communication. When gas leakage is detected, immediate alerts are sent to the user, and safety actions can be initiated. Additionally, when the gas level falls below a predefined threshold, the system automatically places a booking request for a new gas cylinder. The proposed system enhances user safety, reduces manual intervention, and ensures uninterrupted gas supply. This approach provides a smart, reliable, and cost-effective solution suitable for modern smart homes and industrial environments.
