Animation description:

My anemometer produces a sine wave output, which could be measured digitally directly into a computer USB port. I attached it to my oscilloscope to see frequency changes, which match wind speed changes. It could also be attached to a frequency counter, like in the higher end digital multi-meters. I also tried recording it as audio and listening directly with a very good quality earphone. The subwoofer sounds were amazing.
