How to Detect Biogas and LPG Leakage with an Intel Edison based Gas Sensor System

From instructables user antoniraj:

I am one of those 300+ instructables community members who received the Intel Edison Board and specialty Intel IoT development kit offered by instructables under the theme Environmental & Agriculture. One of the proposal submitted by me was a Biogas leakage detection system using Intel Edition and the IoT development kit. I am quite new to Intel Edison and Arduino Programming and it took me more than a month to learn the basics. I have made this project as simple as possible so that anybody can follow the steps in making one at their home.

Most of us use Liquefied Petroleum Gas (LPG) at home for cooking. I have also installed a Biogas plant which supplements about 40% our gas requirement. LPG and natural gas like Methane are odorless gases. However, Ethanethiol, commonly known as Ethyl mercaptan, which possesses a distinctive odor is added to LPG which makes it possible for us to easily detect in the event of any gas leakage. It is impossible to detect the presence of pure Methane as it is odorless, colorless and non-toxic. If you inhale Methane you will feel little suffocation as it displaces Oxygen in the lungs, other than that inhaling small amount of Methane does no harm. However, Methane is extremely flammable and can explode at concentrations as low as 5% in air.

The aim of this project is to detect the presence of Methane in case of any leakage from the Biogas stove and the gas pipe line inside home. This system can also be used to detect LPG leakage.
