## What is ZephyrPro Wind Meter?

This application brings the functionalities of an Anemometer (Wind Speed Meter) and of a Wind Spectrum Analyzer to your iphone (ipad/ipod). 
 
No sensors required: realtime wind speed reading just using your iphone microphone.

The typical wind range is 1-16 m/s (with a small trick, up to 30 m/s: see the user guide): the full scale is limited by the internal mic maximum SPL

Unique features & advanced calibration: simply the best!

>>ZephyrPro at a glance

Dynamic and Average wind speed measuring modes with real time charts.

Wind direction detection

Settable measuring units: m/s, km/h, mph, knots, Beaufort

Settable wind smoothing factor, useful to stabilize measures/graphs with variable winds in Dynamic mode.

Settable average period, useful to stabilize measures/graphs in Average mode.

Wind Spectrum Analyzer with real time chart.

Settable cutoff frequency of the wind band, in order to avoid some specific interference.

Panel & Chart data exporting

Advanced calibration.

Embedded user guide.


>>Quick start
The application relies on the mobile microphone signal. To achieve the best results consider the following:
1)  Easy calibration (only the first time): click on the calibration button (for details read the user guide accessible from the calibration page)
2) avoid measurement in presence of loud noises (heavy traffic, motorbikes, trucks, loud talking, shots)
3) keep your fingers away from the microphone and keep it in a vertical position
4) orient the front of the iphone in the direction of the wind without interfering with your body
5) click on one of the function buttons (Dynamic, Average, Spectrum)
6) A click on the PLAY button starts the measurement
7) A click on the RESET button clears the current measurement
8) HINT: for long observation periods (> 1s) read the AVG value, for medium observation periods (1s) use the Average mode, for short observation periods (gusts) use the Dynamic mode.

This application is not meant to be used in place of scientific instrumentation, but with a good calibration it can come close to a real anemometer device.

Read the embedded User Guide (reachable from any setting button): for any info or troubleshooting you can contact us at support@gaiacons.com.

### 5/5 — Amazing

*2023-08-09*

I wasn’t too sure of the app app first. But I have run some tests. Turns out to be very accurate. Are use it to collect data from glo.gov for NASA and it’s been accurate like nothing I’ve ever seen before. It’s amazing how the device works with the phones microphone, one complaint that I do have is calibration is real easy to understand, took me a few test things to figure it out to good app for determining on the fly one speed.

### 1/5 — Why won’t this app open??

*2021-09-02, version 4.0*

My autistic son really likes this app and uses it on my iPhone. Why can’t I get this to open on my iPad? It actually says “works on this iPad” but it doesn’t!!!!

### 5/5 — Easy to use.

*2018-07-08, version 3.3*

Gets close to the mark.  Handy for boating
