wind speed

Hi, I have a question about windMonitor example , in this code the goal is to send data to NMEA2000 ,this data is PGN,priority,wind speed, wind angle ,wind apparent ,

void SendN2kWind() { static unsigned long WindUpdated=millis(); tN2kMsg N2kMsg;

if ( WindUpdated+WindUpdatePeriod<millis() ) { SetN2kWindSpeed(N2kMsg, 1, ReadWindSpeed(), ReadWindAngle(),N2kWind_Apprent); WindUpdated=millis(); NMEA2000.SendMsg(N2kMsg); } } so the question is how you mesure the wind speed and the wind angle cause i find this function double ReadWindSpeed() { return 10.3; // Read here the wind speed e.g. from analog input } which means the wind speed is 10.3 ,it's a value that you wrote it ,it is not mesured with a sensor can you explain me ? ,please

The example is for how to use NMEA2000 library. You can write double ReadWindSpeed(); function as you like to get real wind measurement.

Thank you So in this case you don't use sensor for reading windspeed ?

No. This is example for using NMEA2000 library not for reading any sensor.
