LPMS-U2 Series: 9-Axis Inertial Measurement Unit / AHRS with USB, RS232, TTL and CAN Connectivity
NOTE: This is a legacy device. For new applications, please refer to LPMS-U3.
Description
The LPMS-U2 sensor series is a series of miniature 9-Axis IMU (inertial measurement unit) / attitude and heading reference system (AHRS) with variant communication interfaces like USB, RS232, TTL and CAN-Bus . The units in this series are very versatile, performing accurate, high speed orientation and relative displacement measurements.
Through 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-U2 series can communicate with the host system either via a USB, RS232, TTL or CAN Bus connection. Depending on the configuration of the sensor, data transfer rates of up to 400Hz can be reached.
This series is a perfect fit for both machine and human motion measurement in size- and cost-sensitive applications. All sensors contain 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.
Particularly, the LPMS-CU2 sensor’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 parameter settings of all sensors can be freely configured using our LPMS-Control software.
