Abstract
A hydrogen detection device includes a hydrogen sensor and a detection circuit, wherein the hydrogen sensor includes: a first electrode; a second electrode; a metal oxide layer; a first insulating film (insulating film); a first terminal and a second terminal that are connected, through a via, to an other surface of the second electrode opposite a principal surface of the second electrode; and a third terminal connected, through a via, to an other surface of the first electrode opposite a principal surface of the first electrode, and the detection circuit includes: an ammeter that measures (1) a first resistance value between the first terminal and the second terminal and (2) a second resistance value between the third terminal and at least one of the first terminal or the second terminal; and a control circuit that selectively outputs one of the first resistance value or the second resistance value.
