Abstract
A progressive, or graded, passive moisture detector is configured to provide an indication of the amount of moisture to which a moisture-sensitive substrate has been exposed, a duration of time that a moisture-sensitive substrate has been exposed to moisture or the effectiveness of one or more protective coatings at preventing moisture-sensitive components from being exposed to moisture. A progressive passive moisture detector includes a plurality of different passive moisture detectors with different properties. The passive moisture detectors may be arranged in a manner (e.g., a sequence, etc.) that correlates to information the progressive passive moisture detector is intended to provide.
