LPMS-CU2: 9-Axis Inertial Measurement Unit (IMU) with CAN and USB Connectivity

US$ 270



The LP-RESEARCH Motion Sensor CAN bus and USB version 2 (LPMS-CU2) is a miniature inertial measurement unit (IMU) / attitude and heading reference system (AHRS). The unit is very versatile, performing accurate, high speed orientation and relative displacement measurements. By the use of three different MEMS sensors (3-axis gyroscope, 3-axis accelerometer and 3-axis magnetometer) low-drift, high-speed orientation data around all three axes is achieved. Additionally, temperature and barometric pressure allow accurate altitude measurements. LPMS-CU2 communicates with the host system either via a CAN bus or USB connection. Depending on the configuration of the sensor, data transfer rates of up to 400Hz can be reached. The LPMS-CU2 fits both machine and human motion measurements for size and cost sensitive applications.

The unit contains a 32-bit digital signal processor capable of running all calculations on-board in real-time. For more information on our sensor fusion method please refer to the IMUcore description.

LPMS-CU2’s CAN bus interface allows connecting the sensor to a larger CAN bus infrastructure. The sensor supports a minimal CANopen implementation as well as a customizable sequential CAN message format. The amount of measurement data transmitted via CAN bus can be freely configured using the LPMS-Control software.
