Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

Allegro has added magneto-resistive sensors to its Hall-based range of current and magnetic field devices, for high-sensitivity high-bandwidth applications. The first product is a 5A 1MHz isolated ...

This file type includes high resolution graphics and schematics when applicable. The latest generation of 3D magnetic position sensors from ams AG uses a pair of sensor elements (pixels) that make it ...

Quantum tech is going green. A new take on highly sensitive magnetic field sensors ditches the power-hungry lasers that previous devices have relied on to make their measurements and replaces them ...

Nuclear magnetic resonance –based co-magnetometers are essential tools for applications ranging from inertial navigation to geophysical exploration and biomedical sensing. Their performance critically ...

With a few exceptions primarily at the quantum-physics level, sensors of real-world parameters are inherently analog. The formal designations of the parameters being sensed are fairly clear, such as ...

Quantum devices that measure Earth's magnetic fields could help replace GPS—if researchers can figure out how to tell when such devices are working well, or even at all. A Pentagon contract suggests ...
