I guess I split/moved this OK...

Hi. I'd love to hear your suggestions. One of the hard requirements is that there are no moving parts. Otherwise, I'd like to use a standard tipping bucket. The "no moving parts" requirement also means that a standard anemometer cannot be used either. The issue is about reliability, specificially that maintenance has to be minimal and the devices have to have a long deployment life. If you know of a rain gauge that doesn't have moving parts, please let me know and I'll check it out. At the moment, the RG11 is the main one I'm evaluating although I'm investigating acoustic rain gauges and also one that seems to be based on conductivity. I don't mind talking about the project in public and the design will be completely open source. It might be better to discuss it in the Remote Weather Monitoring sub-group though.

You need an ultrasonic wind meter - the guts of this basically:  http://www.weathershop.com/davis_windscribe.htm

Oh heck - here is the whole thing:  http://www.sparkfun.com/tutorial/WeBBS/WeBBS-Final%20Report.pdf

Have you considered the New Mountain NM-100?

No moving parts, but I think you'll still need the RG-11 for rain.

Thanks for the suggestions! For that wind sensor, I'll bring it up with the some of the scientists that I'll be talking to. It's sweet, but it might be out of the target price range for this project. We're supposed to get together to discuss this project in about two weeks. The Sparkfun weather station also looks interest. I'm going to have to study that.

Updated: Ha ha ha. I just realized that weather station was probably one of the first devices that Sparkfun put out. Funny to see how silly they were back then. Still silly, but a bit more serious these days
