Abstract
A hydrogen leakage detector includes a sensor and a microcontroller. The sensor is sensitive to a concentration of hydrogen in air. A sensitive unit of the sensor is exposed directly to an in situ concentration of the hydrogen. The microcontroller is programmed to generate and output an analog signal corresponding to concentration information, based on a concentration measurement from the sensor, and to generate and output an analog signal indicating a correct operation of the detector.
