I am looking for a suitable low-cost humidity sensor for a "wearable" battery operated (low voltage / low power consumption) application within a high temperature (+125 degree C could reach +150 degrees) environment. The aim is monitor drying conditions within an industrial hot air dryer type operation which is drying wet objects. High temperatures would last from about 20mins up to 90mins. Electronics + alkaline or coin cell battery thermally insulated in suitable casing (just in case).
Any suggestions.
