The MicroStrain 3DM-CX5 family of high-performance, industrial-grade, board-level inertial sensors provides a wide
range of triaxial inertial measurements, computed attitude, and navigation solutions.
In all models, the Inertial Measurement Unit (IMU) includes direct measurement of acceleration and angular rate,
and is fully temperature-compensated and calibrated over the operating temperature range.
The use of Micro-Electro-Mechanical System (MEMS) technology allows for highly accurate, small, and lightweight devices.
SensorConnect software is a user-friendly program for device configuration. MIP Monitor (MicroStrain Inertial Protocol)
can also be used. Both packages provide configuration, live data monitoring, and recording.
Alternatively, the MIP Data Communications Protocol is available for custom interface development and easy OEM integration.
The sensor operates independent of computer platform, operating system, or coding language.
