I know this may be getting off subject a little but for those interested in switching software from WL or Cumulus over to Weather Display.... WD has a nice slope adjustment that would work. I just downloaded and impressed, my biggest problem I have 4 years of data on Cumulus and website data all using Cumulus lot's of work to change over.

Anyway the slope adjustment at -3% looks like it would work, here's the PDF. I tried it out and works.
There is a setting for decreasing slope as humidity drops lower end of scale also which I have checked.  It doesn't show on PDF however.

Nice! Personally donít care for WD. I personally donít want to keep doing calibration offsets etc. Iím thinking about giving the 75 a try if I can set everything up without soldering. Iím hoping someone on here can tell me how to install the SHT-75. And Iím also curious too if the 75 needs a filter cap?

Will note that Sensirion says that the SHT-75 is designed for weather stations

Could he possibly have one of those DAVIS FARS that had the fan running backwards?

Does the air flow OUT from the top (correct) or OUT from the bottom (BAD)?

I have a few of these and a new 75 coming in tomorrow from Newark. They should work. We'll find out tomorrow. No soldering required.

Iím not very knowledgeable with this stuff so here is my question.

1. If I order a SHT-75, what all exactly I need to do to put it together so that I can use it in my FARS?

Be advised. If you were using an old (non green dot) wetherlikIP logger and you get a new console, you'll need to buy a new Logger too... ask me how I know.. ](*,)  actually, don't ask.

I have unplugged the fan and the problem doesn"t go away  it makes no difference if its  a hot day or mild day  it all has to do when the sun is activating the solar panel.

This is interesting. I would think that the response would be less active is the fan was off, unless it was a windy day that day. But your saying it made NO difference. Hmm
 At any rate, I agree with most here that the temp swings are the result of the sun heating the air and the temp sensor actively and immediately showing this change in temperature because the air is not stagnated in the chamber. In other words.. its doing what its designed to do.

Do the kids ask to hang their volleyball net over those wires?  \:D/

Yeah I know  :lol: There is actually a split level in the yard just right of the first photo, so the cable is about 7-8 ft over the ground most of the way.

I thought about moving the ISS and rain bucket out there too, But My anemometer and UV/Solar also separated and mounted on a pole on the roof peak... so gonna be wires anyway I do it unfortunately.

Sure Miller A!

Anyone can add to it whatever they like!


The original poster, bingobobbo over on AW, should get the credit though!
