Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

Graphene-based Hall sensors represent a significant advancement in magnetic field measurement by harnessing the exceptional electrical and mechanical properties of graphene. Owing to its atomically ...

Diodes Incorporated has launched its first automotive-compliant 3D linear Hall-effect sensor. The AH4930Q detects the magnetic field in the X, Y, and Z directions, enabling high-precision contactless ...

New applications for linear output Hall-effect sensing such as current measurement require both high accuracy and increased sensor bandwidth. The Allegro A1360, A1361, and A1362 programmable linear ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

This file type includes high-resolution graphics and schematics when applicable. In the seemingly endless quest for higher motor performance and improved system cost efficiencies, motor manufacturers ...

The difference between Hall-effect sensors and Hall elements. Why Hall-effect sensors provide more than on and off information. How Hall-effect sensors can detect magnetic fields from an extended ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...
