BMM150 is a low-power and low-noise 3-axis digital geomagnetic sensor to be used in eCompass applications. BMM150 combines harmonically with an inertial measurement unit (IMU) consisting of a 3-axis accelerometer and a 3-axis gyroscope like Bosch Sensortec’s BMI055. By means of sensor data fusion software tailored to the hardware, also available from Bosch Sensortec, the solution determines the absolute spatial orientation as well as motion vectors with high accuracy and dynamics.
