   Zinc chloride. A little dab 'll do ya.

   DO keep it off the wires though, hence
   my 'epoxy-dip' rec  :-)

   The "KEEPING it wet" can be more of a problem.

   Fine if the unit is on your back porch, but what
   if it's an environmental station 90 miles back
   into the hills ?

   As said, there ARE some - kinda iffy - ways to
   detect water vapor that can fit into a kinda
   small/cheap package. It just depends on HOW
   accurate you need to be. If plus/minus 15%
   is functionally OK then ......

   But I did do work for a commercial greenhouse
   long long back ... for max yield they needed
   more accurate figures.
