Automatic Gas Stove with Advanced Safety Features

Gas stoves are now very common in all houses including urban and remote areas. The main power source for gas stoves are either LPG or biogas. Biogas is more cost effective compared to LPG. In both cases chemical energy stored in the fuel is converted into heat energy and this heat energy is used for cooking purpose. Explosive range of LPG is 1.8%-9.5% volume of gas in air. Biogas mainly contains methane as its flammable agent. The leakage of LPG or biogas accompanied with a small spark will results in a huge explosion that can even takes several life. So as a matter of safety leakage should be known in its early stage and should be compensated. The main source of the LPG is fossil fuels, so its huge consumption will definitely lead to its shortage in the near future. So to make sure the availability of fossil based fuels for future generation it is our responsibility to use the fuels at it minimum and avoid all wastage of fuels. In this paper, we report the automation of gas stove which will result in the minimum wastage of fuel and reduce the human interference in the process. This paper describes the distinct properties of LPG that favours its flammability. Some advanced safety features like alarm and automatic message sending facility during gas leakage is also reviewed. Analysis of percentage of reduction in gas wastage and sensing capacity of the sensors are also discussed.
