Well, Edmund Scientific sells a complete humidity sensor/display
module for not terribly much ($20 or $40) that you could probably rip
the sensor out of.  Pretty inaccurate over temperature if I remember
correctly, though.  I suspect that the humidistats in furnaces and
home humidifiers use the old standby - horsehair - which expands and
contracts with the RH.
