    @tmassey After you purchase your nifty new hygrometer with racing stripes, please send me your old school "eye ball."

    :) I remember using what was a state of the art hygrometer years ago. It consisted of a box with a fan and a couple of thermometers-one had a little cotton sock that was soaked with distilled water. I say state of the art, because it had a fan-the other units were similar except the thermometers were in a device one swung around to create the airflow necessary for taking the reading.

    Ok, I'll play the dummy, what's wrong with using a Arduino based hygrometer?
