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 ...

This article is a technical document of Allegro’s Hall effect sensor integrated circuits, how these devices were built, and how Allegro use the Hall effect principle to develop these devices. It ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

A team of researchers from Osaka University and Leibniz Institute for Solid State and Materials Research developed the world's thinnest and lightest magnetic sensor matrix sheet system that visualizes ...

Magnetic actuators and sensors are used to produce and control motion. Applications include systems such as automotive anti-lock brakes, computer disk drives, and factory automation. In many of these ...

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.

Quantum mechanics states that electrons have two stable spins—up and down. With the advent of nanoscale fabrication methods, device companies are harnessing this knowledge to create devices. The ...

Magnetic sensors detect moving ferrous metal. The simplest magnetic sensor consists of a wire coiled around a permanent magnet. A ferrous object approaching the sensor changes magnetic flux through ...

One of the primary ways that gyroscopic motion can be applied is in the monitoring and/or maintaining of the orientation of an object. A broad array of engineering applications are based on gyroscopic ...
