LPMS-CU: 9-Axis IMU / AHRS / Motion Sensor with CAN and USB Connectivity


The LP-Research Motion Sensor CAN bus and USB version (LPMS-CU) is a miniature inertial measurement unit (IMU) / attitude and heading reference system (AHRS). The unit is very versatile, performing accurate, high speed orientation and displacement measurements. By the use of three different MEMS sensors (3-axis gyroscope, 3-axis accelerometer and 3-axis magnetometer) drift-free, high-speed orientation data around all three axes is achieved. The optional temperature and barometric pressure sensors allow accurate altitude measurements. The LPMS-CU can be connected to a host system either via a CAN bus or USB connection. Communication with high data transfer rates of up to 400Hz and internal sampling processing at 800Hz is possible. The LPMS-CU fits both machine and human motion measurements for size and cost sensitive applications.
