Powered by the wind it measures

An internal generator provides all the power for operation of Etesian Technologies patented anemometer.  No batteries to replace, no "rechargeable" battery, no waiting for the clouds to scatter and the sun to break through the fog.  At just 5 MPH wind speed your wind sensor is on line transmitting data once per second back to the readout.
