Abstract
A device for monitoring humidity in a compressed air system comprises a light emitter; a light sensor; and a hygromorphic element. The hygromorphic element is exposed to a source of compressed air and positioned between the light emitter and the light sensor. The hygromorphic element changes the amount of light passing between the light emitter and the light sensor as the humidity in the compressed air increases.
