[G8NSV]

Has anyone manged to use the pPro2 TX with a professional ultrasonic wind sensor?
I have a Gill Windsonic unit which can out put both serial in both proprietery and NMEA, as well as 0-5Vdc analog data.
Serial I'm guessing is out so probably have to use analog?
The Analog data for direction is output as 0v for 0 degrees, 2.5v for 180 degrees and 5v for 360 degrees.
Speed is 0-5v with the max at 5v being selectable up to 60 M/s

I was wondering if anyone has ever done this and has code for it, if not I'll have to write if myself  

Regards

Hi Bob

I think you will need an additional analog pin on the Nano (TX unit), I'm not sure but afraid there is none available.

Not to worry, I was going to use analog as it works over a far longer distance, however Its probably no more work to code it to use serial data and parse the nmea string.
I assume I'm correct in thinking there is no easy way of using presise direction data, and only the 16 direction resolution of the cheaper sensors?
It would be nice to have the full resolution of the ultrasonic sensor if it were fixable in the code.
I looked at the newer board models but it seems none of those support ultrasonic sensors with serial output either. These are becoming much cheaper from China. but I was lucky enough to find a disgarded Gill model when some old equipment at work was sent for recycling.

Kindest Regards

If you gonna use an analog input for the wind direction, you can get wind directions in degrees from 0º to 359º.
Check on the code how it is done for the Davis wind direction sensor.
