Description

The LPMS-CUAL2 Motion Sensor is a miniature inertial measurement unit (IMU) and attitude and heading reference system (AHRS) with CANBus and USB connectivity. 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) for drift-free, high-speed orientation data around all three axes is achieved. Integrated temperature and barometric pressure sensors allow accurate altitude measurements. The LPMS-CUAL2 can be connected to a host system via an 8-pin connector. High data transfer rates allow sampling rates of up to 400Hz. The LPMS-CUAL2 can be used for both machine and human motion measurements.
