What sensor are you using Héctor ?

I used 7002 in the past, and of course you have to compensate it over temperature (as with all "cheap" sensors). but in practice the deviation 

is not so big.

Moreover, with 7002 you have a huge range and you should design an amplifier for your air speeds of interest.

3 or 4 months ago i made some tests with 7002 sensor (same used on ardupilot)
I found a problem with temperature compensation.

Yes it is,

but depending on the STM32, you can have one or more than one simultaneous channels.

I finished the analog airspeed sensor code (on ADC_3) but i have a question.
My math are correct only when i take the adc resolution to be 12 bits (4096)
Is this correct for the STM32 cpu?
