Modern Device Forum

I have two ver C wind sensors. One works as advertised. The other gives me a value of "nan" with a cover over sensor.
Values look like:
start
WindSpeed MPH nan
WindSpeed MPH nan
WindSpeed MPH 9.84
WindSpeed MPH 10.81
WindSpeed MPH 8.29
WindSpeed MPH 7.01
WindSpeed MPH 0.74
WindSpeed MPH nan
WindSpeed MPH nan

Code:"const float zeroWindAdjustment = 0.2;"
Changing the adjustment does not seem to make a difference
I suspect the device is damaged in some way but having been careful with it and examining with magnifying glass I can see not problems.
Suggestions and help with be appreciated. We went with ver C rather than P for the temp adjustment.

Code:"const float zeroWindAdjustment = 0.2;"

If you can't bring it into calibration by changing the zero wind speed it MAY be damaged BUT
try zeroWindAdjustment with a negative value
Also make sure you have a solid regulated 5 volt supply to the sensor.
