LPG is commonly used for cooking in many countries due to its enconomic benefits and convenience.This paper explores an IoT application designed to measure and display the gas content in houshold LPG cylinders, facititating automatic booking of new cyliders and detecting gas leaks.Typically , the capacity of LPG in a cylinder is not easily monitored; our system addresses this by displaying the current LPG level using a load sensor (SEN-10245).The sensor output is connected to an Arduino R3, which processes the data.Using a GSM module, the system sends SMS notifications to users regarding the LPG level and automatically dials a registered gas booking number when a new cylinder is needed.Additionally , a gas sensor(MQ-6)is employed to detect leaks, enhancing safety by preventing potential gas explosins.The current LPG level is continously displayed on an LCD, and users can track the validity of the LPG users via mobile message when the LPG level falls critically low (below 20%), ensuring timely action This automated system prevents both premature and diaplayed booings and significantly reduces the risk of gas-related accients at home
