The Holybro Digital Airspeed Sensor has a very low offset, a high resolution, and best of all, does not suffer from the noise induced by long cables and offsets in the ratio-metric output on other airspeed sensors. Supported on all Holybro Flight Controller Boards with Ardupilot & PX4.
All standard precision sensors come with temperature compensation. It measures temperature to calculate true airspeed from indicated airspeed, using the static pressure sensor on the Flight Controller. Not affected by the heat of nearby processing components, it is much closer to ambient air temperature than in previous analog sensor setups. Supported on all Pixhawk Flight Controllers, this kit comes with M3 / 6-32 mounting holes.
