Introduction
BMM150 is a low-power and low-noise 3-axis geomagnetic sensor from Bosch for compass applications. It allows measurements of the magnetic field and compass angle in three perpendiculars within a measuring range of 1300uT on X and Y axis and 2500uT on Z axis.
Featuring small size and lightweight, the sensor has a 2-bit DIP switch for I2C address setup, and 4 addresses are available. Based on Bosch’s proprietary FlipCore technology, the performance and features of BMM150 are carefully tuned and thus can offer absolute spatial orientation without calibration, perfectly matching the requirements of all 3-axis mobile applications such as robot navigation & positioning, electric compass, electric map, navigation or augmented reality.
