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 temperature than in previous analog sensor setups. Supported on all Pixhawk Flight Controllers, this kit comes with M3 / 6-32 mounting holes.
Package Includes:
1x MS4525DO Digital Air Speed Sensor
1x Rubber Tubing 100cm
1x GH 4P Cable
1x PT60 Pitot
