Room temperature of liquified petroleum gas (LPG) sensor based on p-La2O3/n-Fe2O3
Recently, owing to environment and safety aspect, interest in utilization of gas sensor is increasing. Gas sensor is used to detect hazardous gas in order to avoid it from spread to the environment. Lanthanum oxide and iron (III) oxide was chosen because of their availability and cost effective. Per...
