LPMS-URS3 IMU Sensor

Description

The LPMS-URS3 Motion Sensor is a miniature inertial measurement unit (IMU) and attitude and heading reference system (AHRS) with RS232 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-URS3 can be connected to a host system either via a RS232, or USB connection. High data transfer rates allow sampling rates of 500Hz.
