Radio Shack WX-200 Weather Station which includes a software page for many different weather stations.

http://www.ambientsw.com/ has software called Virtual Weather Station for Windows 95/98/NT.

Oregon Scientific has a unit like the WX-200 called the WM918. Huger Electronics in Germany is the OEM for these units.

WX200 / WM918 Sensor Information Page An excellent site with information on the internal workings of this weather station.

Other weather stations can be found at Davis InstrumentsMaximum, Peet Bros. and Texas Weather Instruments.

Software:

Y2K!

Important note:  Because the software that comes with the WX-200 is a Windows 3.1 16-bit application.  There may be Y2K issues.  I have not extensively tested the app.  But have encountered a lockup while testing Y2K compliance with my system.  Note: If you don't know what your are doing you can have problems adjusting your clock for year 2000.  I don't suggest you try this even though it does sound simple.

Update:  There seems to be a fix for the Y2K issues.  Appairently AccuWeather & RadioShack did not feel we needed to know this.  As Accuweather does not list the software as being an update but it is newer then the one shipped with my system.  You can get it here.

Update: A newer version with Y2K fixes is at The RadioShack WX-200 Help Page.



Click here to get the status of a Visual BASIC program I'm working on to work with the WX-200.  This project has stalled for some time now.  <sigh>

Click here to download a program by Mike Wingstrom for Linux and Xwindows that displays some of the WX-200 data.
Includes source code. Requires xforms 0.87 and is included in this archive.

Click here to download a program by Tim Witham for Linux that is a client/server for reading data from the WX-200.

Or make your own software:

Below is the format of the weather station's data stream. The vast majority of this info was decoded by Mike Wingstrom. The data is sent at 9600 baud 8n1 (8 data bits, no parity, one stop bit). For an interface cable to a PC 9 pin serial port use a serial mouse extension cable. This PC text document may be viewed or  downloaded. It is tab delimited ASCII so it will load easily into a spreadsheet or database document.  For Netscape you'll have to right-click and select "Save Link As...".  For Internet Explorer right-click and select "Save Target As...".

I have removed the Protocol from the main page to help this page load faster.  You can still view it with the link above.  Perhaps XLS and PDF versions may be available in the near future.

Sorry for the slow updates.  Not much has changed and my interest in the project has lowered since my WX200 got hit by a near by lightening strike.
