A novel quartz oscillator that has a temperature-stable output was investigated for outdoor hydrogen sensing. The output from the quartz oscillator remained almost constant for temperatures in the range of 15 to 50℃. Fluctuations of the output of the quartz oscillator in this temperature range were 0.3% at constant relative humidity of 0%RH, which corresponds to the change in the output when 0.3 vol% of hydrogen leaked in air. This change is thus sufficiently lower than the necessary minimum detection level of 1 vol% hydrogen concentration using the novel quartz oscillator's output during outdoor hydrogen sensing.<br>
