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.

Robust against external magnetic shocks
Low and predictable temperature dependency
Configurable noise and current consumption and ODR

Not available for new designs, we recommend to use BMM350.
