Wet bulb hygrometer/psychrometer topic
« on: January 16, 2016, 01:43:35 PM »
Back in '09, I made a wet bulb hygrometer/psychrometer out of a Davis leaf soil station with 2 temperature probes. I'll find that and move it here...

How did the "calculated" RH numbers compare with the sensor-sourced RH numbers? Close? Biased? or Exact-a-mundo?

As I recall, I determined that the calculated numbers were close, but limited by the whole number temperature outputs of the Davis temp sensors.
