Airspeed Sensors

Airspeed sensors are highly recommended for fixed-wing and VTOL frames. They are so important because the autopilot does not have other means to detect stall. For fixed-wing flight it is the airspeed that guarantees lift not ground speed!

Digital airspeed sensor

Hardware Options

Recommended digital airspeed sensors include:

All the above sensors are connected via the I2C bus/port.

Additionally, the Avionics Anonymous Air Data Computer can be connected to the UAVCAN bus to determine not only high-accuracy airspeed, but also true static pressure and air temperature via onboard barometer and an OAT probe.
