Dallas 1-Wire weather instruments

[KC8HQS]

Does anybody have experience with the Dallas 1-Wire weather sensors? I'm looking at the temperature/humidty & barometer sensors and possibly the lightning detector. I already have a Peet Bros. Ultimeter 100 with the raing guage and I love it but I want to add sensors in a cost effective way. I believe my software will allow this.

Here's the website. Not sure about the company selling these either but I'll take a chance... I like the prices!

I'm under the impression you have build the boards. I've soldered some wires together but that's about the extent of my soldering experience to date. I can get help though. Am I correct in my thinking and how difficult is it to put these together? I'm aware I'll have to buy the USB adapter and probably a hub. I have lots of CAT5 cable.

If I don't purchase these 1-Wire sensors, I'll be upgrading to the Ultimeter 2100 at the Dayton Hamvention in May.

Thoughts? Opinions? Suggestions?

Do NOT make the assumption that the 1-Wire sensors will interface with your Davis WX system.

The 1-Wire® WX station instruments you are inquirying about originated in mid-1990s as a developer/experimenter offering by Dallas Semiconductor - now part of MAXIM INTEGRATED.

Will Beals, N0XGA and Russ Chadwick, KB0TVJ , with expert consulting from the late Dr. R. John Morgan (sk, 1999), developed the T-238 APRS/WX station kit to use these Dallas 1-Wire® WX sensors.

The original T-238 kit was awarded second prize in Circuit Cellar Magazine's - Design99 Contest and
was featured in the May 2000 issue of Circuit Cellar Magazine.
The T238+ was a follow-on offering based on the original design.
TAPR offered these T-238 kits to radio amateurs for several years.

AAG Electronica LLC based in Laredo, TX assumed production (Mexico and Texas) of the actual Dallas/MAXIM 1-Wire® WX instruments and sensors, once the initial Dallas special production of the 1-Wire® instruments ceased.

All weather stations use some type of communication method (wire or wireless) between the remote (outdoor) sensors and the indoor WX station console (user interface).

Micro-controller Communication interfaces(RS-232, RS-485, 1-Wire, I2C, SPI, etc.) are standardized by companies (de facto) or standards bodies (IEEE, EIA/TIA).
