I am VERY interested in a reasonably priced heated ultrasonic anemometer.
But it would have to be completely plug & play (compatible) with Davis. Other than the additional power requirements for the heater.
Even though I currently use Weather Display for it's website tags support,I don't want to be dependent on it. My primary data storage/archives are with WeatherLink and to a lesser degree MySQL via Davis WDTU.
The Hongyuv introduction documents lists the power requirements as DC 5-30V, 10ma@12V (without heater). I would like to know what they are WITH the heater.
Added: Note it would need to be compatible with the Davis 6332, VP2 Anemometer Transmitter Kit

It looks like I'm going to bite on this. I've had a good email correspondence with Stefan there and I know Ryan W will be trying one of their ultras and may add it to his inventory if all goes well. The WDS2E with heater, no solar panel, Davis compatibility, and 20m of power cord (2 wires for heater, 2 for power) will cost me $489. The heater automatically turns on at 0°C. I may install a switch near the plug that will allow me to manually turn off the heater. It really doesn't need to run 24/7 in the winter. I posted the heater power requirements in the first post.
And it should work no problem with the Davis 6332 (I use one too). You just need to set the wind cup size to "other" so that the VP2 doesn't make any adjustments to the raw data. We'll see how it goes...I'm tired of bearings going on my anemometers after a couple years.
The ABS plastic with this concerned me, but Stefan told me it's UV stabilized like the Davis rain cone. Still, I think I'll stick with the black option instead of the white (you have the choice of either).
The only bummer is you're stuck with the Davis resolution of 1mph.
