The system supports I²C or SPI communication, operates from 3.3 V or 5.0 VDC, and is temperature compensated for reliable performance in dynamic environments. Featuring dual-port architecture and high update speed, it is suitable for flow and airspeed measurement applications up to 200 m/s, simplifying integration into embedded, aerospace, UAV, and industrial platforms
This high-speed dual pressure measurement electronic system has been developed for demanding aerodynamic, pneumatic, and embedded sensing applications where fast response, stable readings, and simple integration are essential. The board is built around the MS4525DO pressure sensor from TE Connectivity, a ceramic-based digital pressure transducer designed for high-performance OEM applications. This sensing element combines pressure and temperature measurement in a compact PCB-mount format and incorporates advanced internal conditioning electronics, digital conversion, and factory calibration to deliver dependable output under dynamic operating conditions. It provides digital pressure and temperature data with high resolution, using a 14-bit pressure output and 11-bit temperature output, while supporting I²C or SPI communication for straightforward integration into embedded control systems.
Beyond the sensing element itself, this board is conceived as a complete electronic measurement solution, integrating the sensor, electrical connector, and the required signal adaptation into a single compact assembly. The inclusion of dedicated interface and conditioning design helps ensure clean communication and stable acquisition, reducing the risk of false readings caused by poor wiring practices, supply instability, or unsuitable signal routing. The sensor itself requires proper local decoupling, including a 100 nF capacitor placed close to the device, and the board design takes these requirements into account to support robust and repeatable measurements in real installations rather than only in laboratory conditions.
The MS4525DO is fully calibrated and temperature compensated, with a total error band below 1% over the compensated range, and offers a typical update time of 0.5 ms, making it well suited to high-speed pressure and airflow monitoring. In this implementation, the dual-port architecture enables precise differential pressure measurement for airspeed and flow-related applications, supporting systems operating at speeds of up to 200 m/s. The sensor operates from 3.3 V or 5.0 VDC, and its rugged ceramic construction, digital output architecture, and integrated signal conditioning make it an excellent foundation for reliable measurements in aerospace, UAV, test bench, environmental control, and industrial platforms.
