In this area of pitot tubes and air flow sensing, I work with some researchers who have developed a tiny MEMS sensor that may have very interesting applications in air flow sensing (e.g. direction of winds, velocities etc)
However, before bringing this to the mainstream forum, I thought of bouncing this off you first to see whether you opine it to be as interesting as I think it is. You do seem to be someone well versed in the air flow sensing space for drones.
Could you drop me an email at email@example.com ? Anyone reading this who is interested, feel free to drop me a mail too!
