Holybro Standard Precision Digital Airspeed Sensors (MS4525DO/PT60 Pitot Tube)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
