TMP,OUT_pins readings

Hi, so i noticed the analog voltage read from the TMP,OUT pins a wave, pictures below
i supply the sensor with stable 12V from a linear PSU
can you please help me where i gone wrong? is it supposed to be like that?

i try to read them to ADS1115 then to arduino uno and same there the results are ...

Re: Wind sensor REV P - adding compensation

no worry friend.
where can i check for updates? when the new results will be ready,

i am using the sensor with the equation that comes in the Arduino code
when comparing to my anemometer the result are not equal but close.

generally i like this sensor it got some nice advantages:
- small can get ...

Re: Wind sensor REV P - adding compensation

yeah that's exactly what i did.
but then when taking those values and use them
to calc the wind speed with the temperature compensation what do i do?

as i understand i need to put them in the regression equation:
WS_MPH = (((Volts – ZeroWind_V) / (3.038517 * (Temp_C ^ 0.115157 ))) / 0.087288 ) ^ 3 ...

Wind sensor REV P - adding compensation

Hi,
so i am trying to calculate the wind speed from the equation derived from the regression
(ie with temperature compensation)

i don't get good values.. always something very very small.
please your help, i don't know where i got it wrong and i quadtripled checked everything

exapmle:
Volts=2.444 ...
