The main purpose of this paper is to portray a method of showing the level of gas in a gas cylinder so that it gives us an idea of the level of gas remaining in a cylinder. It can be used in homes as well as industries where gas cylinders are big and are almost impossible to detect the level of the gas. It enables the user to book a gas right on time so that user doesn’t have to worry about an empty cylinder. Furthermore, sometimes the leakage in the gas cylinder cannot be detected by human nose and requires more sophisticated equipment to detect these gases in order to avoid any mishap, in this project whenever Gas leakage is detected, there is a display on the LCD(3) along with a message sent through GSM(2) modules to our GSM(2) module alarming the user about this Leakage so that some action can be taken. It avoids accidents caused by GAS Leakage in cylinders. Furthermore, this project also includes Analysis of the gas used in every month, and will indicate which month has a high gas usage and similarly would also indicate months of lower gas consumption, it will help companies who manufacture gas cylinders for both domestic as well as Industrial purpose.
