PX4 Differential Airspeed MS4525DO Airspeedometer Airspeed Sensor for Pixhawk2.4

Product Description

PX4 Airspeed Sensor

Airspeed sensors are highly recommended for fixed-wing and VTOL frames. They are so important because the autopilot does not have other means to detect stall. For fixed-wing flight it is the airspeed that guarantees lift not ground speed!

• The Pixhawk digital differential 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 the APM 2.6 analog airspeed sensor.

• 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 Pixhawk 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 MS5611 static pressure sensor on Pixhawk.

• 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 and PX4 autopilot generation boards, this kit comes with M3 / 6-32 mounting holes.

Airspeed meter kalibratie inleiding:

ARSPD_BUS set as 1,use EXTERNAL I2C

ARSPD_SKIP_CAL set as 0, each time restart the flight controller, need to calibrate the airspeed meter offset. Set to 1, automatically skip the airspeed gauge offset calibration, using the last calibrated offset

ARSPD_TUBE_ORDER set as 2,Automatic matching of the upper or lower tube is dynamic pressure

ARSPD_TYPE set as 1, use I2C-MS4525D0

In the ground station debugging interface, observe the change of the airspeed meter. The general value jump is 1-3 in the normal range. Blow air to the airspeed meter. If the airspeed value increases, the airspeed meter works normally.
