AoA Sensor

Is there an AoA sensor that can be used with PX4? Preferably one that is integrated into the pitot tube?

How do you measure AoA with just a pitot tube? Or did you mean something else?

So you meant “something else”, like: https://www.grc.nasa.gov/www/k-12/airplane/tunp5h.html

You could go with a multi-hole probe for both angle of attack and sideslip, but its a bit pricey for what you get. The vanes have proven more sensitive for me at lower airspeeds.
