I bought an indoor/outdoor weather station. The brand is Accurite.
It is a nifty setup that has outdoor remote sensors for temperature,
humidity, wind speed, wind direction, gives indoor temperature, barometric
pressure and a lot more. The problems, though, is the temperature readings.
They are 4 degrees low. IMO, that makes me suspect of everything else it
reads and is really about useless when it comes to a freeze warning.
I'm probably going to return it, but I'm wondering if anyone had good
experience with another brand in the less than $150 range?
That's a good question Ed. It doesn't take much of a distance in areas
for differences. Possibly you have something much more accurate that you
know is in calibration?
But if it's always 4 degrees and always low, I understand your suspicions
and would probably come to the same conclusion.
I compared it to three other thermometers that all read the same. One was
calibrated with ice water at 32 degrees. In addition, the indoor reading
was 67 while the actual was 71. At 67, my wife would have been under a
For close to $100, I don't want to have to make mental changes every glance
at the temperature, plus it will be off with relative humidity and wind
chill calculation that it also reads. The place the readings were taken is
within inches of each other.
That should work most of the year but the crickets tend to be quit at 5
I did some searching and found a Zephyr Instrument model that is supposed to
be accurate to 0.5 degrees. That is a more sensible tolerance.
A practical solution is to use a human body temperature thermometer for
calibration. While they have a very small range (~96F - 104F) of
resolution, you can count on them to be accurate.
It would also be interesting to use a non-contact thermometer and hit the
signal off of the sensor element of the weather station.
Thanks for the pointer to Zephyr brand!
Googled Zephyr Instrument. Which one were you looking at? This one caught my eye.
Nice toy. I've always been drawn to these on display in stores. Why I
dunno but never saw anything of this quality & functionality. Not 50
bucks but lots of ooo's and ahhh's for the buck.
I just ordered this one. I don't mind the blemish to save a lot of money.
By any chance have you come across the manual for it online? Be nice to
go over before it arrives. Did not see it on supplier/mfgr site.
My status shows as shipped but all the UPS site says is that they
received electronic shipping info but do not have the pkg yet.
No manual available on line that I can find. My order was shipped and will
arrive on Monday. The shipping weight is 9 pounds. You either get a lot of
stuff or a very heavy carton.
It will be a while before I can install the computer software though, my
computer is going to the shop tomorrow and will be a few days. The other
unit I had came with two outdoor units and the temperature sensor I put
under the deck out of the direct sun. The wind and rain will go on the deck
rail for now. I don't have a really good place for them without going to
the roof. Tall trees on two sides, detached garage have to affect wind
I was just going to get the TB without software anyway until you posted
the link to the TD-X with software at a much much better price. Hope the
inside unit easily clips on and off the the wall mount should I want to
plug the USB cable in. I do have a long USB cable with a booster but that
would be a PITA.
As far as the install, just do the best for what I have to work with. I
really know nothing about these but it seems some of the temp sensors can
be installed in the sun because they have a radiation barrier.
I found this about general installation recommendations but like I said,
just do the best for what I have to work with.
Good information. No problem with the temperature and humidity sensors. I'm
not so sure I want togo up on the roof for the wind though. I'll have to
compromise on that.
As for the main unit, my intention was to just leave it in the familyh room,
but the computer is at the other end of the house. I can dowload, but it
woudl be nice to have it connected for real time stuff so I may do that.
Here's a couple of pics of the installd unit. Probably a couple of little
things I could to to reduce any eyesore.
Piece of PT attached to fascia with a couple of screws to hold during
install. Mast attached to PT with 4x pipe straps and 2" galv screws. 2"
used so it penetrates PT and fascia board. Ain't coming off.
Supplied pole fits snugly inside mast pipe. Drilled hole clear through
both and put in machine screw and locknut.
Rain gague bracket spans junction of supplied upper pole to secure and
keep from turning.
Temp gague mounted with 10x1" screws into 3/4 strip.
Still ain't gonna survive a garbage can hit...
Couple of concerns about location but best I could do for what I have to
work with. Possible warm air collecting under soffit because siding below
gets sun in afternoon. Gable vent off to the left, Should breeze be
blowing from the left I guess it could drift over and have an effect.
