Abstract This paper reports on a set of experiments designed to develop a workable gas
sensor prototype using an electronic system with methane. The current is found to be
sensitive to the presence of methane gas, which is a conduit for a variety of gas sensors. The
sensitivity is shown to depend on pointed or broad electrode configurations. Scanning
electron microscopy images show the area of conductance that determines the quality of the
electrodes in three configurations. Data processing is performed with a support vector
