MS4525DO Digital Airspeed Sensor Module for Pixhawk and UAV

The MS4525DO is a high-performance digital airspeed sensor designed for fixed-wing UAVs and vertical takeoff drones. Featuring an advanced I2C interface, a ultra-low total error band, and a 14-bit resolution differential pressure transducer, this module delivers real-time airspeed and temperature monitoring to prevent aircraft stall.
分类:
The MS4525DO is an ultra-stable electrochemical and piezoresistive digital output pressure transducer optimized for drone flight control systems. Operating seamlessly with Pixhawk, Ardupilot, and PX4 hardware, this ceramic-based sensor offers dual sideport configurations to easily connect with standard pitot tubes.
Engineered with internal CMOS conditioning, the MS4525DO eliminates standard analog calibration issues by transmitting calibrated 14-bit pressure and 11-bit temperature signals simultaneously. It works perfectly within a single 3.3V or 5.0VDC supply voltage range.
Key Features:
  • High Precision: Offers 14-bit digital pressure resolution and ±0.25% span accuracy.
  • Dual Sensing capability: Integrated combination of temperature and differential pressure readings.
  • Advanced Protocol: Communicates via a fast I2C interface (7-bit address 0x28) for plug-and-play setup.
  • Thermal Protection: Fully calibrated and temperature compensated with a Total Error Band under 1.0%.
  • Lightweight Architecture: Extremely small footprint ideal for payload-sensitive remote aircraft.
Upgrade your navigation system with the authentic MS4525DO to secure precise aerodynamic velocity data during demanding flight missions.
