magnetometer

I'm waiting for a startup to use the magnetometer in the smartphone to auth.

I suppose under some reality that is more secure than assigning magnetometer to everyone.

I just cleared security where I was effectively given my choice of magnetometer, backscatter, or groping.

The removal of magnetometers is a very bad thing security-wise.

It works, but requires infrastructure to be installed, so any system using just a magnetometer/inertial system would be very useful.

It's basically a magnetometer aka a digital compass.

Accelerometers tend to gain error factor very quickly without using a form of sensor fusion such as a partnership with a magnetometer to cross reference things like yaw with.

I'm surprised at how there are only 3 major components in the schematic: a STM-32 microcontroller, an accelerometer/gyroscope, and a magnetometer.

Assuming there's not too much iron and steel in the land fill, it's might be possible he could find it with a sensitive enough magnetometer at 1 meter, maybe more so if you built a motor to move it around rapidly.

How many reviews include information about the quality and calibration of the gyroscope, motion sensor and magnetometer systems?

If a three axis magnetometer was used in conjunction with electrical nerve stimulation on multiple sites, you could have the full range of compass heading, local magnetic field density and ac field sensing.

My tldr is: magnetometer and ground penetrating radar indicate more stonehengy stuff under stonehenge; researchers need more money to dig and find out more; previous researchers have ruined the area in the middle by digging.

With tango on the horizon there will be a point in time phone could know where its at by simply comparing geometry, or at the very least augment camera view with accurate directions based on the scene geometry, and not crude 'somewhere this way' gps+magnetometer Arrow.
