Product overview
The JHEMCU MS4525 INAV PIX PX4 FC AIRSPEED is an airspeed measurement module for fixed-wing and vertical take-off and landing aircraft. It measures aircraft speed relative to the surrounding air to help support stable flight and landing and avoid stalling in windy conditions. Built around an MS4525 sensor, it operates at 4.7~5.2V and supports Ardupilot, PX4 and INAV firmware. The sensor weighs 3.6g, while the airspeed tube weighs 16.8g and measures 92mm long by 14mm in diameter.
The PIX version uses a differential pressure sensor with digital output through an I2C interface, with total error below 1.0% within the compensation range. The airspeed tube’s long end connects to the upper dynamic pressure port, and its short end connects to the lower static pressure port. For Pixhawk installations, the sensor connects through the controller’s I2C port or an I2C interposer board module. Calibrate the airspeed sensor after installation.
