Hey John! I have a doubt. Doesn't how fast the thing rotates actually depend on the material with which its made? For the same dimension, would the one made of material with higher density would weigh more and hence rotate slowly?
I have a solar tracking unit, It has +,-,Signal for the anemometer input. The anemometer that I have only has two wires. (Red, Green) How do I hook it up???? Can you help???
