Yes, we are interested in this question, too. Please respond online.
Also, we are using Hobo Dataloggers to track RH, temp. and light. It has a
nice graphics component, but we want other statistics like how quickly are
the conditions changing and to what extent. Is anyone doing further
manipulation of this kind of data? And if so, what kind of additional
statistics are you gathering?
Thankful for this list,

Subject: Relative Humidity fluctuations
I have a question.
I understand that RH should not fluctuate more than a certain percentage
over a given 24 hour period.
But within that 24 hours, what is an acceptable time difference for the
fluctuation extremes occur? For example, in charting the RH I have found
cases where the minimum and maximum for a day are just half an hour
apart--clearly too intense a change. But are the min/max time differences ok
if they are, say, 6 hours apart? 12? At which point should I be
concerned/what should I aim for?
Thank you all,
Astrida
