Description
The MS 4525DO Air Speed Sensor and Pitot Tube Set is designed to provide accurate airspeed measurements for drones and UAV systems. Using a digital differential pressure sensor, it measures the difference between static and dynamic air pressure through the pitot tube to determine true airspeed.
This data is sent to the Pixhawk flight controller via an I2C interface, allowing autopilot systems such as ArduPilot or PX4 to maintain stable flight, optimize throttle control, and prevent aerodynamic stalls. The module includes a pitot tube, tubing, and connection cables for easy installation.
The sensor provides high resolution and low noise measurements, making it suitable for aerial mapping, long-range flights, and research applications.
