A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables ...

This application note presents some of the fundamental information about Hall-Effect sensors. It also presents the basics of magnetics, and the added value of programmable sensors and sensor interface ...

A novel magnetic sensor for the first time detects tiny fluctuations in a small magnetic field -- even when there is a strong magnet right beside it. The sensor can thus be utilized even in places ...

While most sensors that surround us and make modern technology possible are well-known and understood, magnetic sensors used in magnetometers are often overlooked or misunderstood, even though they’re ...

This article introduces Allegro’s ACS71x current sensor integrated circuits (ICs) without concentrator that can control and minimize external magnetic field interference. These devices can boost ...

A new scanning microscope developed at Brown University can uncover defects in the smallest and most complex integrated circuits at a resolution 1,000 times greater than current technology. The ...

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 ...

Because it requires no battery that must be recharged or replaced, and because it requires no special wiring, such a sensor could be embedded in a hard-to-reach place, like inside the inner workings ...
