Description
The LPMS-B2 Motion Sensor is a miniature inertial measurement unit (IMU) and attitude and heading reference system (AHRS) with wireless Bluetooth connectivity. The unit performs accurate, high speed orientation and displacement measurements with three different MEMS sensors. 3-axis gyroscope, 3-axis accelerometer and 3-axis magnetometer provide for drift-free, high-speed orientation data around all three axes. Optional integrated temperature and barometric pressure sensors allow accurate altitude measurements. The LPMS-B2 can be connected to a host system via Bluetooth Classic 2.1 and Low Energy 4.1 to a PC, mobile device. High data transfer rates allow sampling rates of up to 400Hz and up to 7 LPMS-B2 units can be used simultaneously with one host system.
