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

Description: The altitude sensor si an absolute pressure sensor that will that will measure the pressure inside the airplane, where the perturbation due to airspeed are low. It will be interfaced with an microcontroller that will retrieve 6 values: rough temperature, rough pressure and 4 calibration data. After some computation, the compensated pressure and the corresponding alitude will be sent on request to the central processor through I²C.

Scheme of the module: Altimeter
