1. A sensor, comprising:
a detection device including a first detection portion and a second detection portion; and
a circuit portion,
the first detection portion including a first detection element, the first detection element including a first conductive member and a first detection member,
the second detection portion including a second detection element, the second detection element including a second conductive member and a second detection member,
the circuit portion being configured to execute a first detection portion operation for outputting a first detection result corresponding to a first detection value based on the first detection member when a first current is supplied to the first conductive member,
in a case where a first evaluation value is not within a first range, the circuit portion being configured to execute a second detection portion operation by the second detection portion,
the first evaluation value including at least one of a value based on the first detection member when the first current is not supplied to the first conductive member or a value based on the first conductive member when the first current is substantially not supplied to the first conductive member.
