I have tried a few different weather stations, so I can unequivocally tell you what NOT to get. DON'T buy anything under $300. *sigh* Unfortunately the cheap ones are total garbage. The recent one I
Davis has wired and unwired versions - but you did say cheap and they are not. I bought a wired weather station for similar reasons and it has been fine. However I can make the PC stop seeing it - US

DON'T buy anything under $300. *sigh* Mine cost 40 something, works fine, is made of cheap plastic. Uses plain old Duracell non rechargeable. Last 2 years or more outside. The ones indoors only last
I should mention one other thing about the "cheap" weather station anemometers that drive me crazy. The first WX station I had only updated the wind speed about every minute. The LaCrosse updates abo
The outdoor unit uses a small solar cell to charge a small (but several Farad) supercapacitor and a small battery. Battery replacement is easy, repair/replacement of the supercap is a little dicey, b

I have a wireless davis vantage pro and have not experienced any trouble at qro power levels. I shunt feed my tower for 160 meters and have not had any issues. Service or technical help (parts) by Da
I have a Davis Instruments Vantage Pro 2 solar powered wireless system. It works flawlessly, even in the presence of kilowatt RF. It uses 2.4 GHz frequency-hopping and Davis claims 1500 foot range. I
The Davis wired version, which I am using, has a 4 second delay for wind, and direction display. That can mean the loss of 10 to 20 mph in a gust situation. Tom KD8DEG I should mention one other thin
I'm not sure that's true about the wind. I have a Davis Vantage Vue. The remote unit does some processing to generate a 2 s mean speed and a peak gust value within the 2 s window. Data are then sent

Chris KF7P I don't know of any wireless battery/solar powered powered that are real time. They have to have enough battery power to run a couple of days and all night. To do that the calculate haw lo
I believe the Davis Vue is a newer generation than the Vantage Pro and Vantage Pro 2, so all bets are off as to how it measures and transmits data. FWIW my (wireless) Vantage Pro 2 seems to underesti
The unit I have is the Davis Vantage Pro2 wired, and the 4 second delay is what Davis tech support told me when I questioned the accuracy of the wind readings that were being displayed. Tom KD8DEG I'
I can't speak to the Pro2 model, but any anemometer must average over a period. I was incorrect about the Vue: it yields 4 s averages in each packet. Sonic anemometers average over something like 10
Yes, I have the InSpeed Vortex cup-type (i.e., non-directional) anemometer mounted on the tip of my mast at the top of my tower. It uses a simple magnet to close a reed relay switch once per revoluti
Not to pound the InSpeed drum, especially since I have no connection to them at all other than as a long ago customer, but InSpeed also sells a high resolution anemometer for $89 that puts out 8 puls
Regardless of the specific instrument, ANY digital measurement system will require some amount of time to sample the transducer output. The time required depends on the resolution of the transducer,
You're calculating windspeed from rotational velocity. The latter is probably measured using either an optical sensor or some electromagnetic device. In either case, you're counting pulses over a spe
