Can someone recommend a reasonable Wireless Weather Station for less
than £175.00? It should have a clear display and humidity.

Oh, and where's the best place to buy it? Any help would be much
appreciated. Thanks

My LaCrosse WS-3600 would meet your requirements. Accuracy, particularly
regarding wind speed, is a little questionable, but temperature seems
pretty accurate, as does rainfall (given that it measures in 0.52mm
chunks).

Rain gauge broke down after about 7 months and was replaced by the
company I bought it from under guarantee. Occasional bad data comes over
the link which I have to edit out or correct.

Results can be seen at http://users.aber.ac.uk/ais/weather/ (using the
Open3600 software plus stuff I've written), but it comes with Windoze
software.

I can't comment; I've not been altogether happy with the service from
the people mine came from, so won't recommend them.

you think of the 'La Crosse Technology WS-8035U-AL Wireless Weather
Station'?

Hello, Planet X,

I too use the La Crosse WS-3600. There are more expensive units but I
find mine matches my venerable max-min thermometer pretty well and
seems to track the closer 'official' sites when it comes to pressure.

Like your previous respondent I have doubts about the anemometer. In my
case, though, I suspect that it's because I have fairly tall trees
around the site. By that I mean that, although light breezes affect the
device quite well, the stronger gusts are deflected 'up and over' the
unit even though it's mounted some 12 metres above the ground.

The rain gauge is a bit rough when it comes to fine readings but this
can be overcome by enlarging the collection area. Should you do this
you will need to do a calculation to determine the correct rain level
when you read the results shown on your console.

I hope that all makes sense.

Forgive me for butting into this thread. I'm a total newbie to weather
stations but am thinking of buying one and the WS-3600 would seem to meet
my requirements.

Not quite sure of a couple of things. I assume the wind sensor would need
to be mounted as high as possible - e.g. top of chimney? How is the wind
sensor (and rain sensor) connected to the temperature sensor ? Or is it
wireless direct to the base station ? If by cable - what length is the
supplied cable(s) ?

Where would I position the temperature sensor and rain sensor ?

TIA - sorry for being so clueless :-)

Regarding the WS-3600:

I'll leave the pros to comment on the ideal siting of the anemometer.

How is the wind
sensor (and rain sensor) connected to the temperature sensor ? Or is it
wireless direct to the base station ? If by cable - what length is the
supplied cable(s) ?

Wind and rain sensors are both connected by wire to the temperature sensor.
The temperature sensor sends back wirelessly (or wired if you prefer) to
the base station.

Where would I position the temperature sensor and rain sensor ?

Again, one for the experts.

If I had the money, I'd buy a Davis. Unfortunately, I haven't.

Hugh,

From my limited experience:

1) Anemometer - the standard recognised height is 10 metres. If you
can't make that then the highest you can manage.

2) Rain gauge - in the clearest area you can find on your site. By that
I mean the best area you can where trees and buildings will have the
least affect on your readings.

3) Temperature and hygrometer units (in the case of the WS-3600 these
are in the same housing) - out of the sun, preferably in an airy spot.
The unit in question does have a shield around it but experimentation
results tell me that direct sunlight will affect your readings.

4) Cabling - the WS-3600 comes (well, mine did) with 10 metres of cable
for the anemometer, the rain gauge and the wired link from the main
sensor unit. The latter I have not used, preferring to use the radio
(rf) link back to the console. You can, though, extend the cabling. I
have done that with extra 10M lengths using standard telephone cables:
Note though that I had to re-terminate them because of their poor
connections even though they worked quite well when tested with a
'phone.

5) I really shouldn't be here. I live some 16,000 Km from the UK. If
you wish for further advice then e-mail me.

Airports have 'em at 10, standard height is 3. For agricultural use
they're usually set at 2m.

Twice the distance as the height of the nearest tall object IIRC...
with the top of the gauge 300mm above ground. It's also supposed to
be 200mm diameter and set with a spirit level.

Inside a Stevenson screen, with its floor 600mm above grassed ground
IIRC.

In spite of my Davis station complying with none of those, except the
anemometer height, it agrees surprising well with the nearest
official met station.

John H makes some good points, Hugh.

Unfortunately most of us are not in a position to comply with all of
the requirements of a 'proper' weather station.

If you are interested then by all means go he

http://www.bom.gov.au/inside/oeb/networks/20131.pdf

and download the file.

As best I know it's up to date and complies with the WOM.


Oh, yes - best read it first rather than print it as it's over 90 pages
in length. The file is between 660Kb and 700Kb.

Thanks to all of you for your replies - very helpful.
