摘要

PROBLEM TO BE SOLVED: To allow easy finding of an unsuitable thermal management in a commodity distribution process.SOLUTION: The device to be attached to an object includes: a detection unit for detecting a motion of the object whose shape changes in response to variation in temperature; a determination unit for determining whether the magnitude of the motion satisfies a predetermined condition; and a storage unit. When the magnitude of the motion satisfies the predetermined condition, the storage unit stores the date when the predetermined condition is satisfied.
