空速传感器

对于固定翼和 VTOL 机架，强烈建议 使用空速传感器。 它们非常重要，因为自驾仪没有其他方法来检测失速。 对于固定翼飞行来说，保证升力的是空速而不是地速。

Hardware Options

Recommended digital airspeed sensors include:

• MEAS Spec series (e.g. MS4525DO (opens new window))

  • mRo I2C Airspeed Sensor JST-GH MS4525DO (opens new window) (mRo store)
  • Digital Differential Airspeed Sensor Kit (opens new window) (Drotek).

• EagleTree Airspeed MicroSensor V3 (opens new window) (eagletreesystems)

• Sensirion SDP3X Differential Pressure Sensor (opens new window)

• Holybro Digital Air Speed Sensor (opens new window)

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

注解

Additionally, the Avionics Anonymous Air Data Computer (opens new window) 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.

配置

PX4 setup information can be found in: Basic Configuration > Airspeed.
