MS4525DO Digital Airspeed Sensor w/ Pitot Tube for Pixhawk

This sensor accurately measures the indicated airspeed of fixed-wing aircraft, providing critical data to the flight controller. It is essential for maintaining stable flight, especially during takeoff, landing, and autonomous navigation. The digital output ensures precise data for Pixhawk and PX4 autopilots, enhancing overall flight performance and safety for various UAV operations.

The MS4525DO integrates temperature sensing directly within the module, allowing for the calculation of true airspeed from indicated airspeed. Unlike older analog setups, its proximity to ambient air temperature rather than internal processing components provides more accurate thermal readings. This compensation is vital for consistent flight performance across different environmental conditions.

No, the MS4525DO airspeed sensor is specifically designed and usable only with fixed-wing flight code within Pixhawk and PX4 autopilot systems. Multi-rotor drones typically do not require an airspeed sensor for stable flight, as their flight dynamics rely primarily on IMU and GPS data. It will not provide functional benefits for multi-rotor applications.

The MS4525DO sensor module comes with M3 and 6-32 mounting holes, offering flexibility for integration into various airframe designs. This universal mounting standard ensures compatibility with common hardware used in UAV construction, facilitating straightforward installation into existing or custom fixed-wing drone builds without extensive modifications.

The MS4525DO features a measurement range of 1psi, allowing speeds up to 100m/s (360km/h). It boasts a high resolution of 0.84Pa, ensuring very accurate airspeed readings for demanding flight scenarios. Data is delivered at 14 bits from a 24-bit delta-sigma ADC, providing robust and reliable digital output for flight control systems.
