1. An occluded hydrogen content estimation method implemented by an occluded hydrogen content estimation device, the method comprising:
estimating a content of hydrogen occluded in a metal due to a change in humidity through at least one repetition of a wet state to a dry state to generate an occluded hydrogen unit content;
determining a period after a target metal is placed in an area and determining meteorological data corresponding to the period for the area where the metal is located wherein the target metal is a same type is the metal, and
estimating a content of occluded hydrogen that is absorbed in the target metal for the period based on the occluded hydrogen unit content and the meteorological data corresponding to the period.
