For my first learning project, I’ve interfaced a Davis Instruments anemometer and wind vane to, respectively, a SNAP-AIRATE card, and a SNAP AIR40K card. Also A Hydreon RG11 rain sensor configured as a 0.001" per tip tipping bucket rain gauge emulator.
The anny is a magnetic sensor that “closes” once per rev of the wind cups. The direction is a 20K continuous turn pot.
Everything works and I can see the raw values change in a watch window in PAC Control. (The tach module might not be the best for this, as the threshold for the anny is 1 mph = 1 rev in 2.25 seconds. But the module came with the system I bought on ebay, so I thought I’d try it out.)
The question right now is, what’s the proper way to scale/calibrate the 0-20K pot to 0-360 degrees?
