The design of Sky-Sailor is shown below (click on a part to have more information)

Description: The airspeed sensor is basically a differential pressure sensor that will be connected to a "Pitot tube" located in the wing. It will measure the pressure and the temperature and give a compensated value of the pressure, proportionnal to the square of the speed. The airspeed sensor will communicate with the central Processor directly through I²C.

Scheme of the module: Airspeed sensor
