MD0550 Airspeed Sensor Calibration Dataset — Wind Tunnel Experiment with UT-363 Reference

MD0550 Airspeed Sensor Calibration Dataset — Wind Tunnel Experiment with UT-363 Reference
This dataset contains full calibration results for the MD0550 analog airspeed sensor, measured inside a custom-built subsonic wind tunnel.
Data was acquired using a UNI-T UT-363 digital anemometer as the reference instrument.

The experiment was performed under two airflow conditions:

• Laminar flow (with honeycomb flow straightener)
• Non-laminar / turbulent flow (no honeycomb)

More than 100+ measurement points were collected across both configurations.
