HolyBro Digital Air Speed Sensor – MS4525DO

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 Autopilot Flight Controller Boards with Ardupilot & PX4.

Featuring a Measurement Specialties 4525DO sensor, with 1 psi measurement range (roughly up to 100 m/s or 360 km/h or 223 mp/h), the Airspeed Sensor Kit enables a resolution of 0.84 Pa, with data delivered at 14 bits from a 24 bit delta-sigma ADC. It also measures temperature to allow calculation of true airspeed from indicated airspeed using the static pressure sensor on the Flight Controller. Not influenced by the heat of nearby processing components, it is much closer to the air temperature than with previous analog sensor setups. Supported on all Pixhawk Flight Controller, this kit comes with M3 / 6-32 mounting holes.
