Description

The Holybro Digital Air Speed Pitot Tube employs an advanced MEMS differential pressure sensor to deliver precise airspeed readings, a critical parameter for autonomous flight modes, stall prevention, and optimizing cruise efficiency in fixed-wing and hybrid VTOL UAVs. Its digital output minimizes analog signal noise, providing cleaner data to the flight stack for more responsive and stable control.

Engineered for field reliability, the unit features a ruggedized housing that protects the internal sensor from moisture, dust, and vibration. The integrated heating element option (if applicable) prevents ice formation in cold-weather operations, ensuring consistent performance. Its design prioritizes minimal aerodynamic drag and straightforward mounting on wing leading edges or fuselage pylons.

Key Features

  • High-precision digital differential pressure sensor for accurate indicated airspeed (IAS).
  • Direct I2C interface simplifies wiring and integration with Pixhawk-series and other modern flight controllers.
  • Durable, weather-resistant construction using reinforced plastics and sealed connectors.
  • Low-power design suitable for long-endurance mapping and surveillance drone missions.
  • Calibrated and temperature-compensated output for consistent readings across operating environments.
  • Standard mounting footprint and included hardware for secure installation on various airframes.

Applications

  • Fixed-wing UAVs requiring accurate airspeed data for autonomous navigation, loiter, and landing phases.
  • VTOL (Vertical Take-Off and Landing) transition drones for monitoring airspeed during forward flight modes.
  • Racing and long-range FPV fixed-wing platforms to prevent stalls and optimize throttle management.
  • Mapping and survey drones where consistent cruise speed is critical for sensor coverage and battery efficiency.
  • Research and development platforms for aerodynamic testing and flight data logging.

Frequently Asked Questions

What flight controllers is this Holybro Pitot Tube compatible with?

The pitot tube is compatible with any flight controller supporting I2C peripheral communication and standard airspeed sensor drivers, including all Pixhawk-series (Pixhawk 4, 5, 6X), Cube variants, and any system running ArduPilot or PX4 firmware. You will need to connect it to an available I2C port and enable the airspeed sensor within the flight stack's parameters.

How do I install and calibrate the Digital Air Speed Pitot Tube?

Mount the pitot tube on the aircraft's fuselage or wing leading edge in clean, undisturbed airflow, ensuring the static pressure port is correctly oriented. Connect the I2C cable to your flight controller. Calibration involves a ground-based procedure (often zeroing the sensor) followed by an in-flight calibration pass as detailed in your flight controller's (ArduPilot/PX4) documentation to map raw sensor data to accurate airspeed.

What is the operating voltage range, and how is it powered?

The sensor operates from 1.8V to 3.6V. It is typically powered directly from the flight controller's 3.3V rail via the I2C connection. Ensure your flight controller provides a clean 3.3V supply. The low voltage range makes it unsuitable for direct connection to a 5V or LiPo battery source without a regulated step-down.
