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.

1-8. (canceled)
9:
- A hydrogen leakage detector, comprising:
- a sensor sensitive to a concentration of hydrogen in air, the sensor including a sensitive portion exposed directly to an in situ concentration of hydrogen, the sensor being structured to output information corresponding to a concentration measurement;
- and
- a microcontroller programmed to:
- generate and output an analog signal corresponding to concentration information, based on the concentration measurement, and
- generate and output an analog signal corresponding to a status of the detector.
The detector according to claim 9, wherein the analog signal corresponding to the status of the detector indicates a correct operation of the detector.
The detector according to claim 9, wherein the microcontroller is programmed to verify one or both of:
- an integrity of the sensor, and
- an integrity of one or more components of the microcontroller.
