P6 wind sensor is the latest revision of our wind sensor, revised to increase stability and accuracy. We also added a high precision potentiometer to allow easier calibration. All boards are calibrated in the shop, so the potentiometer shouldn't need to be changed by the user, although it's there to experiment with if you so desire. The Rev. P wind sensor is an improved hot wire anemometer, similar to our Rev C wind sensor, but including hardware compensation for ambient temperatures. The P refers to positive temperature coefficient thermistors that are used in this model.  These thermistors are more stable and more absolutely accurate than the thermistors on the Rev C. These thermistors require a higher voltage to heat the sensing element to operating temperature. Thus the sensor needs an 9-12 volt supply.  One pleasant side-effect of this increase
