Abstract
A sensing circuit includes a first sensing element, a second sensing element, a reduction unit, a storage unit, a specifying unit and a detection unit. The reduction unit reduces the amount of the energy applied to the second sensing element. The storage unit stores a degradation characteristic of the sensing element. The specifying unit specifies a rate of degradation. The detection unit detects the amount of the energy on the basis of the rate of degradation.
