Stearic acid was deposited on surface of 9[MHz], AT-cut quartz crystal microbalance as gas sensing material using Langmuir-Blodgett(LB) technique. We measured gas response between deposited LB films and organic gas for special temperature(0, 25, 50, 80℃). The resonant frequency changed due to absorbance of organic gas such as methanol, ethanol, propanol and butanol gas at special temperature. As a result, the resonant frequency responded to organic gas at 0, 25 [℃]. but, the resonant frequency almost not responded to organic gas at 50, 80[℃].
