LPMS-UTTL3 IMU Sensor

Description

The LPMS-UTTL3 Motion Sensor is a miniature inertial measurement unit (IMU) and attitude and heading reference system (AHRS) with USB and TTL 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-UTTL3 can be connected to a host system either via a USB or TTL connection. High data transfer rates allow sampling rates of up to 400Hz. The LPMS-UTTL3 can be used for both machine and human motion measurements.
