I am looking for any suggestions as to reliable inexpensive electronic
weather instruments.

With several units that I have tested from places like Target, Walmart,
Radio Shack I find that they are not repeatable, readings drift and
will die when the weather gets cold.

Has anyone found a source or brand that they have had good success
with?

Any leads or links to building your own instrumentation?

Thanks

Circuit cellar had an article on that a year or two ago.

search circuit cellars website you'll come up with a ton of designs.

"reliable" and "inexpensive" are at best orthogonal, if not downright
contradictory...

I just want the stuff to work. Had a heathkit weather station for a
number of years, but when I worked 2m packet, it thought I was on
jupiter -- temperatures zoomed down and barometric pressure went
really, really high (and that was *after* I put RF bypassing on a lot
of high Z nodes, and shielded the thing).

I've had no trouble with the Davis Instruments stuff. Currently run
Vantage Pro2 stations at a number of locations, using the Weather
Display software.

It's not cheap, but it works.

The Dallas 1-wire system has been popular.
North American mfg is in Mexico and
I saw that a European mfg started to build the same design.

Thanks for the leads so far....

Has anyone actually built any of this designs and hooked it to a
laptop?

If so, I would love to hear about it...links and pictures would be
great.

If you look, you will find very few sites talking about actual efforts.

You might like to have a look at the Silicaon Chip website - they
published a weather station not so long ago - I read the articale at the
library so don't have a copy, but a search of their site should find it -
the windspeed/direction part looks very neat and should be reliable and
cheap

Texas Weather Instruments developed the 1-WireT Weather Station, using
technology licensed from Dallas Semiconductor (see Sensors magazine June
1998), to solve the problems of attaching multiple cables, power supplies
and consoles associated with weather instruments to a Windows PC.

AAG Electronica (Mexico) makes the kit of parts ($75), the TWI is only an
assembled unit.

Has anyone had any experience with this weather station?
