Re: Reliable Inexpensive Electronic Weather Instruments

here's another...

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

If you want something reliable and accurate you will have to spend some money.

Check out Maximum for wind gauges. Do a google or click here:

"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.

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

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