I have a question hopefully someone out there in net-land can answer?

We (a group of 17 Electronic Eng 3rd Year Students) have a 12 week
design project for designing a Micro Controller for a domestic
clothes dryer. After extensive market research (looking in the
local dept. store) found that humidity controlled dryers were
rare - hence our desire to use the exhaust air humidity as a indication
of the dryness.
 The problem arises as to selecting an appropriate sensor, considering
 the nasty environ.
 Does anyone know of sensors used in commerically availiable products


 Any suggestions/reply would benefit 17 frustrated Eng Students
 (and probably give 'em a better mark too!!!!!!!)

 Thanks
