Magnetometers

Always on the right track: Magnetometers

For any portable device, other motion sensors may tell you where you are and how fast you’re moving, but to find out which direction you’re pointing you need a reliable magnetometer. Acting like a compass, it provides an accurate measurement of orientation in relation to the earth’s magnetic field.

BMM350

BMM350 is a very small, high-performance, and low-current 16-bit 3-axis magnetometer. The digital sensor is ideally suited for a wide range of consumer applications such as AR/VR, head orientation, indoor navigation, magnetic compass, high-end gaming, and dead reckoning. The sensor is based on Bosch Sensortec’s proprietary TMR technology. The BMM350 magnetic sensor offers outstanding design flexibility, providing a single monolithic package solution.

Unique field shock recovery feature
High accuracy and ultra-low noise due to TMR technology
Very low power consumption

BMM150

BMM150 is a low-power and low-noise 3-axis digital geomagnetic sensor to be used in eCompass applications. The 12-pin wafer level chip scale package with a footprint of only 1.56 x 1.56mm² and 0.66mm height provides highest design flexibility to the developer of mobile devices. Applications like virtual reality or gaming on mobile devices such as smartphones or tablets require 9-axis inertial sensing including magnetic heading information.
