ABSTRACT:
A hydrogen sensor1includes detection elements4A,4B,4C formed from hydrogen-absorbing alloys which exhibit different hydrogen-absorbing pressures at a given temperature; a strain gauge6which detects changes in volume upon absorbing of hydrogen by the detection elements4A,4B,4C; a micro-heater2which controls the temperatures of all the detection elements4A,4B,4C to approximate equal values; and a substrate3.
