This document describes a system for automatically ordering LPG gas cylinders and detecting gas leaks. The system uses a microcontroller to monitor gas levels in the cylinder based on the stove knob position over time. When the gas level reaches a threshold, it sends SMS alerts to the user and gas agency. It also has an MQ5 gas sensor to detect leaks and activate an alarm. The system aims to prevent running out of gas and promote safety. It provides a low-cost automatic solution to common problems with manual gas cylinder monitoring and management.
