Davis humidity stuck at 100%
 

Houston, I think we have a problem!

I can't beleive the humidity is still 100% outside, but it's been stuck
on it since yesterday evening. Any ideas/solutions?

You need a cold blast of dry air from the east. Happy New Year

Fat chance of that happening ;-)

I had the opposite problem a few weeks ago. Over a period of a few days the RH
on my Vantage Pro 2 gradually drifted down to less than 5%. I solved the
problem by replacing the temp/RH sensor with one of the new 'enhanced' sensors
which are supposedly more accurate. It has all been working fine since then.

I'm not really sure what caused the problem but it developed shortly after a
spell of wet weather with very strong winds. It's possible that water getting
to the sensor was the problem but I'm only guessing.

MMmm, could do with the the sun coming out and a good drying wind as I
get the feeling dampness has got into the old WMII sensor. I feel like
taking the wife's hair dryer out there, um, better not thinking about it...

It's probably packed up. If it has, I'm afraid that spares are no longer
available, as I discovered when mine suffered a similar fate.

If anyone wants more detail on the *digital* T/H sensors in the Davis VP2
and Vue stations then a detailed description is included in the following
topic on the Davis knowledgebase that we maintain:

http://www.manula.com/manuals/pws/da...midity-general

NB1 This isn't really intended as light reading but the details are there if
you need them!

NB2 All pre-2006 Davis stations (ie WMII / VP1 / early VP2 models) used an
*analogue* T/H assembly which, sad to say, is no longer available from
Davis. Supplies were maintained well beyond the 5-year period which is Davis
policy for the continued availability of spares after the end of production
of particular models, but that stockpile is now totally exhausted.
Occasionally spares may turn up eg on eBay and similar sites.

Sounds like my options a
1. Forget about the hunidity/dew point
2. Get a new system
