Digital Airspeed sensor for Pixhawk with Pitot Tube I2C Interface

Digital Airspeed sensor สำหรับ Pixhawk พร้อม Pitot Tube

ตั้งค่า para ตามนี้ครับ

ARSPD_BUS  set as 0,use internal 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.

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.
