I have a 600-960 mV signal that I want to use to indicate wind direction using the ADC-16 could you point me in the right direction? (no pun intended)

Hi Paul,

I would guess that the best way to go with this, is to measure the angle in degrees from North.

Where 600mV is 0 degrees and 960mV is 360 degrees (I guess the sensor output is designed to be 1mV per degree). Use a scaling look-up table like:

600 0
960 360

See the help file on how to enter these values.

Best Regards,
