None, of the simple thermometer/hygrometer systems I have seen
are very good, I have bought lots of them. If you want an accurate
measure of temperature and humidity you need a high quality weather
station system or a good wet bulb/dry bulb hygrometer. You can
find lots of information on weather stations at Ambient Weather.

One system I have used is from Sensatronics. It is a handy multi
probe system you can hook up to monitor your greenhouse, I have one
monitoring my greenhouse and I too two probes and set them to a wet
bulb/dry bulb system to track the humidity in my greenhouse. For
me the nice this about it is the ability to track it all over the
internet. I have a computer monitoring my system and my greenhouse
temperature. I bought it as it fit my needs, but it is more than some
people want to spend.

There are some systems being built and played with on the net by
technology oriented people that you can get into that are inexpensive
and can be very accurate, but they are not off the shelf systems. If
you want more information do a Google search on" one wire
temperature". There were some companies trying to build off the
shelf systems with one wire systems. I have not tried any of
them.

I am a beginning orchid hobbyist. I have a digital indoor/outdoor thermometer/hygrometer combination which provides hygrometer readings that just do not appear accurate for my Florida (US) location, nor are the relative humidity readings close to that reported by our weather agency. Has anyone found an accurate thermometer/hygrometer unit which provides for two sets of readings (in and outdoor)?
