A hydrogen sensor is a gas detector that detects the presence of hydrogen. They contain micro-fabricated point-contact hydrogen sensors and are used to locate hydrogen leaks. They are considered low-cost, compact, durable, and easy to maintain as compared to conventional gas detecting instruments. ==Key Issues== There are five key issues with hydrogen detectors: * Reliability: Functionality should be easily verifiable. * Performance: Detection 0.5% hydrogen in air or better * Response time < 1 second. * Lifetime: At least the time between scheduled maintenance. * Cost: Goal is $5 per sensor and $30 per controller. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「hydrogen sensor」の詳細全文を読む スポンサード リンク
