HikerBob, Peter,

Good points!
I will look at the differential between the simplified Dew Point Calculation and the more complex logarithmic method in the next couple of days. My application is more geared towards frost elimination which typically occurs with relative humidity well below the 50% which is the recommended floor for use of the simplified formula. I will fire up excel and do the comparison.
An no, I have not looked at the Arduino. I had planned on using a PIC or utilize the original Atmel MCU00100 Starter Kit which I have mothballed as well as AT90S8515s. Then I ran into the calculation complexity. Looks like I have some homework to do.
Will keep you posted.

Tom
