Description

The Holybro Digital Airspeed Sensor utilizes the MS5525DSO, a next-generation digital pressure sensor designed for high-volume OEM applications. Its integrated 24-bit delta-sigma ADC and factory-calibrated coefficients deliver precise pressure and temperature readings with minimal offset and noise, eliminating the signal degradation common with analog sensors over long cable runs. This makes it ideal for reliable airspeed data in demanding UAV environments.

Engineered for low power and high performance, the sensor supports multiple operation modes, allowing users to optimize for conversion speed or current consumption, with conversion times as fast as 1 ms. Its barbed pressure ports ensure a secure connection to the supplied PT60 pitot tube, providing a complete solution for accurate airspeed measurement in fixed-wing and VTOL aircraft.

Key Features

  • High-Resolution Digital Output: 24-bit digital pressure and temperature data via SPI or I2C interface ensures accurate, noise-immune readings.
  • Ultra-Low Power Design: Operational current of 1 µA and standby under 0.15 µA maximizes flight time for long-endurance UAVs.
  • Robust Pressure Range: Measures from 1 to 30 PSI, suitable for a wide spectrum of UAV airspeeds and flight profiles.
  • Fast Conversion Speed: Configurable for rapid sampling down to 1 ms, enabling real-time flight control feedback.
  • Factory-Calibrated Accuracy: Internal calibration coefficients provide high accuracy out of the box, simplifying integration.
  • Compact SOIC Package: Small outline IC package with barbed ports allows for easy mounting and reliable tubing connections.
  • Full Compatibility: Supported by all Holybro autopilot boards and seamlessly integrates with ArduPilot and PX4 firmware.

Applications

  • Fixed-wing UAVs requiring precise airspeed data for efficient cruise control and stall prevention.
  • VTOL (Vertical Take-Off and Landing) transition aircraft for accurate forward flight speed management.
  • Long-range and endurance mapping/survey drones where power efficiency and reliable telemetry are critical.
  • Racing and aerobatic fixed-wing models for performance tuning and data logging.
  • Research and development platforms integrating airspeed feedback into custom autopilot algorithms.

Frequently Asked Questions

What is the operating voltage range for the Holybro MS5525DSO Airspeed Sensor?

The sensor operates from 1.8V to 3.6V DC. It is designed to be powered directly from a standard 3.3V rail on most flight controllers, ensuring compatibility without the need for an additional voltage regulator.

How do I connect this sensor to my Holybro flight controller running ArduPilot?

Connect the sensor's GH 4-pin cable to a free I2C or SPI port on your flight controller. In ArduPilot parameters, enable the airspeed sensor and select the correct bus type (I2C or SPI). The sensor's factory calibration is typically automatically applied.

What are the benefits of a digital airspeed sensor over an analog one?

Digital sensors like the MS5525DSO transmit data via I2C or SPI, which is immune to voltage drop and electrical noise over long cable runs. This results in more stable and accurate airspeed readings compared to analog sensors, which can suffer from signal degradation.

Can I use a different pitot tube with this sensor?

Yes, the sensor features standard barbed pressure ports. You can connect any compatible pitot tube using the supplied or similar rubber tubing, as long as the tube's pressure range and physical connection are suitable for your application.
