Hi edr1924,

in the software of the TX module main tab beginning from line 100 you can find the different impulse <-> wind speed correlations of the different devices. Depending on which anemometer you want to emulate you can calculate a output frequency corresponding to your actual wind speed.

Thanks, yes I have to go that route, changing the WD software itself. 
I was hoping to make a Davis 6410 compatible 'plugin' converter but alas...

Hi edr1924,

I don't think you have to change the WeahterDuino TX Software. Your converter can just emulate the Output pulses of a davis anemomenter.
My idea would be:
- You converter determines the actual windspeed in m/s - from the comments in the TX Software you can calculate which frequency of pulses corresponds to the windspeed of e.g. a davis Anemometer.
Then you simple calculate back your frequency according to the actual windspeed and output it on a digital I/O.

You will have to be aware of the potential of the output depending on your voltage source of the converter you will have to use a galvanic isolation.
