LP-RESEARCH Motion Sensor Bluetooth version 2 (LPMS-B2)

LPMS-B2: 9-Axis Inertial Measurement Unit (IMU) with Bluetooth 2.1 and 4.1 Connectivity

Measurement Unit (IMU) / Attitude and Heading Reference System (AHRS).
Versatile device, performs accurate orientation and relative displacement measurements at high speed.
By using three different MEMS sensors (3-axis gyroscope, 3-axis accelerometer and 3-axis magnetometer), low-drift, low-latency orientation data is obtained around all three axes. In addition, temperature and barometric pressure sensors allow you to accurately determine the altitude at which the unit is located.
The LPMS-B2 communicates with the host system via a Bluetooth Classic 2.1 or Low Energy 4.1 connection.
Multiple LPMS-B2 units can be connected simultaneously to a single host system (maximum 7 units on Windows/Android), reaching bit rates up to 400 Hz.
