Accelerometer: 3 axes, ±20/±40/±80/±160m/s² (16 bits); Gyroscope: 3 axes, ±125/±245/±500/±1000/±2000°/s (16 bits); Magnetometer: 3 axes, ±4/±8/±12/±16 gauss (16 bits); Barometric Pressure: 300 to 1100hPa. Data output format: Raw Data; Euler Angle; Quaternion @ up to 400Hz. Power supply 5 to 30vDC (RS232), 5vDC (USB). Dimensions: 34 x 34.5 x 15.7mm, weight: 20g. The LPMS-URS2 includes a DB9 serial port for RS232 output and a micro USB port for USB 2.0 output. Units supplied with Micro USB cable, User guide card and 1 year warranty. Software: C++ library for windows, LpmsControl software and Open Motion Analysis Toolkit (OpenMAT) for windows.


The LPMS-URS2 Motion Sensor is a miniature inertial measurement unit (IMU) and attitude and heading reference system (AHRS) with USB and RS232 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-URS2 can be connected to a host system either via a USB or RS232 connection. High data transfer rates allow sampling rates of up to 400Hz. The LPMS-URS2 can be used for both machine and human motion measurements.
