Magnetic sensors quietly underpin everything from smartphone compasses to the stability systems that keep electric vehicles on the road, and the race to make them smaller, faster and more sensitive is ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

A NIMS research team has developed a new experimental method capable of rapidly evaluating numerous material compositions by measuring anomalous Hall resistivity 30 times faster than conventional ...

Hardware developer and Maker Salim Benbouziyane has created an open-source, fully functional 6-DoF (six degrees of freedom) ...

This energy management interface is the "brain" of a self-powered, battery-free sensor that can harvest the energy it needs to operate from the magnetic field generated in the open air around a wire.
