What the World Needs Now -- Big Dial Wind Speed Indicator


  

Previous Issues

January 27, 2012

My new home in Lubbock Texas is blessed, or cursed, with lots of wind.  At times the gusts can reach 60MPH.  When the wind is about 40MPH, we have found it impossible to do any work in the back yard.  What I would like to see is a wind speed indicator with an easy to read big dial, similar to many outside temperature dials.  Perhaps the dial would be about 12 inches in diameter with a clear plastic cover.  With such a device can look outside and determine if it is too windy.

The system might consist of a standard 3 cup anemometer.  The frequency of the pulses generated by the device’s internal magnet rotor would be proportional to the wind speed.  The frequency would be converted to a voltage.  That voltage would then be converted to an angle by a servo motor.  The servo control might provide about 270 degrees of rotation.  With a calibrated dial, the readout might range from 0MPH to 60MPH.  The whole thing might be powered by a combination of a rechargeable battery and a small solar panel.  I solar powered white LED spot light might be turned on at night, so the dial could be read at night.  We often have high winds in the middle of the night.
