I'm taking the liberty of repeating a query
I sent to this list some time ago.

I've been reading the list since then
(at the time it had been suggested to me elsewhere
that my query should be directed here),
and am fascinated by the quantity of data reported.
How do you all collect it?

But my query was (and is):
Does anyone have experience of a weather station
sending back information over the internet,
preferably by WiFi through a WiFi-enabled ADSL modem,
but possibly by USB connection to a remote computer?

The general advice that I have received
is that the Davis Wireless Weather Station VP2
is the best choice, though it requires an additional dongle
if it is to send information back directly over the internet
(through an ADSL modem accepting WiFi input).

I'm not very clear how the apparatus is actually set up,
eg whether one can just put it on the roof,
or if it has to be mounted someway from the house?

Any advice or enlightenment gratefully received.

Not sure that I can add much to the reply I gave previously but let me
summarise again:

Yes there's quite a bit of experience in data comms via WiFi or via
GPRS/GSM (ie mobile phone technology). It's all perfectly feasible,
but there are multiple options and you need to define in more detail
the parameters of what you're seeking to do - eg distance for the data
link (100m or 100km?), frequency of data updates, availability of
electrical power at the remote site, likely budget etc - in order to
get a more specific answer. There's no substitute I'm afraid for doing
some homework on the various options - the website in my sig would be
one starting point if you haven't browsed it already.

As to sensor siting then a few useful primers will be found at:

(a broader introductory guide covering traditional instruments too)

Thanks very much for your helpful response;
I've been looking at your site, http://www.weatherstations.co.uk/,
and will study it more closely.

The weather station would be in a property in Italy,
with information sent back to Ireland over the internet.
There is no problem about electrical power
(though there are surprisingly fierce electrical storms there).
I had more or less settled on a Davis VP2,
until I saw that you needed an extra dongle to connect it
to the internet.
I did google quite a lot, but didn't come across much information
about how to set up the weather station physically,
eg whether the components can be put on a roof, or outside a window, etc.

Basically, it wouldn't really be much more than a toy.
But I'll look at the sites you mention,
and try to make an informed decision.

I am using something similar but slightly different in my method of
getting the information to its final destination. I have a standaloe
computer with the Oregon Scientific WMR968 weather station hooked to
it. This is located at my residence in NE Arizona USA. It is connected
to the internet via wireless to the modem in the next room and thence
via satellite to the net. There is a website called www.wunderground.com
that willl accept the weather data and broadcast it over the internet.
So if I wanted to see what the weather is right now in Rome, (55 F, 25
mph wind from SSE) all I have to do is go to the website and type in
Rome, It and it comes up. You could put the name of the village that
you have the equipment mounted. As far as the instruments are
concerned mount the wind instruments where they will now be affected
by a venturi effect of wind coming off of a roof. I have my temp/
humidity sensor inside my wellhouse so I can also monitor the temp in
it. At present the rain gage is not set up, but it will be mounted on
a flat piece of metal on a pipe in an open area. After you get it
setup, you have to register with the website and you are operational.
Make sure you don't have to many firewalls set up. Mine quit for a
while until I realized this morning that I had 2 firewalls setup and
it wasn't getting through. The software is FreeWx-Wi and as the name
implies its free. I tried a some of the others but this seems to work
with the least amount problems. If you would like to see the data
from my station, go to the www.wunderground.com website and type in
KAZCONCH5 in the search box.
