This paper deals with the systematic product design methodology and development of liquid petroleum gas (LPG) level indicator using open source software Android. Domestic Cooking gas cylinders contain LPG which is used for cooking. Sometimes consumer feels cheated with regard to the amount of gas filed by the dealer. Using LPG gas indicator with the assistance of android, one can easily know the amount of gas present in the cylinder.
