I don't have even $150 sunk into this whole project including the servos, so I'm really hoping to either find samples or something cheaper. I'm really leaning towards the old Honeywell 4000 and Dallas DS2438 but even the 4000 is going for $17 a pop which comes to $136 all on it's own. That they are.

I can't believe humidity sensors are really that much! The SHT15′s are nice looking, but expensive. I can’t believe humidity sensors are really that much!

I'm finding that for low current sensors, a lot of folks are taking DS2438 battery monitors (just a 1-wire A/D converter) and using those to turn any old sensor into a 1-wire device. I'll take a look at these and see if I can convert them, thanks! Not bad, thanks for the suggestion!
