سنسور مگنتومتر سه محوره BMM350

1.Introduction

BMM350 3-axis digital geomagnetic sensor. It can measure the magnetic field strength in three spatial axes and is characterized by low power consumption (200uA), low noise (190nT rms@xy-axis 450nT rms@z-axis), high range (±2000μT), and high sampling rate (400~25/16Hz, selectable).

It utilizes TMR (Tunneling Magneto Resistance) technology and has a unique field shock recovery function. This feature makes the device highly robust to external magnetic fields, thus always ensuring high accuracy under the impact of surrounding magnetic fields.

It can be used for indoor and outdoor navigation and positioning, electronic compass, and AR/VR device application development.
