Rev C with EPS32 return wind speed in thousands (1600)

Post by nattygur »

I'm using the sample code. It is working fine with Arduino.
When I'm using EPS32 i'm getting consistant data, but in thousands.

I tried two configurations:
1 - taking the positive from the EPS 5V pin, or from the USB pin (mot working). the ground for the eps ground pin.
2- I'm connecting the USB +/- wires and the RV C wires to 5V supplier.

I measured that Im getting 5v at the sensor.

I didn't use pins that shut down when wifi is on.

In both scenarios i'm getting high values.

If i change the formula, i can get normal data and it changed in correlation to the wind speed.
for example:
WindSpeed_MPH = pow(((RV_Wind_Volts - zeroWind_volts) /5.2300) , 2.7265); //the original is /0.2300

Any idea?
