Question: How does the windmeter communicate with the phone and the app? Does it plug into the mini-USB port? Or does it plug into the power port and then use BlueTooth or wireless to communicate with the phone?

That is what is so cool about our wind meters design. There are NO cords, no USB, NO bluetooth, NO radio, NO electrical connections whatsoever. It plugs into the audio jack but only to support the sensor it does not use the audio jack for power or any signal.

And our wind meter is far far more accurate than the 99¢ "wind meters" that really just measure wind noise especially for weak or very strong winds where it really matters. Plus you get a wind graph with average, lull, direction and sharing not just an instantaneous reading.

Let's see who can be the first to figure out how the wind meter works. Free custom human Gorge forecast on your next vacation for the first correct answer and the dumbest answer!

I would guess something like project hijack. http://web.eecs.umich.edu/~prabal/projects/hijack/

or... it could use the accelerometer which has a sensitivity of approximately 0.02g and a range of ±2g making the iPhone and iPod touch sensitive enough to analyze the vibration of most moving machinery.

How about the spinning rotor generates a magnetic/electrical field which is sensed by the iPhone's antenna for data input?
Just a thought....

How about a variation on the above: The spinning rotor generates a magnetic field. The magnetic sensor in the phone (used for compass function, I think) detects the period of the magnetic field variation due to the spinning magnets, and then calculates the speed of the wind meter turbine and thus the speed of the wind.

Spinning motor generates a wave signal that produces a pitch based on the speed of the motor. Pitch is converted to windspeed by calibration of the software (done in the lab).

Yes, an improved onsite report system (posting and viewing) is actively in the works.

You'll be able to post your wind report straight from your WeatherFlow wind meter and/or post your own text onsite report.

And, reports will be viewable on:
iWindsurf iphone and android apps, and website
WindAlert iphone and android apps, and website

Would this meter work on the iPhone too?

Hi Airwave,

Yes that wind meter is supported using the same technology we used for our old La Ventana sensor you see in the image below.

All you do is hold your iPhone in your hand and sight towards the sensor. Every few seconds press a button on your iPhone to record the readings of the vane. After 1 minute add up the sum of all of the readings. Then divide that number by the total number of readings to get the average wind. Next input that number into the text box for onsite reports and hit send.

If you are out of wifi or wireless record the average number on a piece of paper and insert into an envelope, seal and stamp envelope and send your reading to Weatherflow's main office.
