Competitive gamers look for every advantage they can get, and that drive has spawned some of the zaniest gaming peripherals under the sun. There are plenty of hardware components that actually offer ...

The new Hall-effect current sensor delivers best accuracy for high-voltage power conversion in AI, automotive, and energy systems. As power converters used in AI data centers, xEVs, and clean energy ...

When the Arduino UNO Q was first unveiled in October 2025, the specifications of the Qualcomm DragonWing SBC listed the ABX00162 SKU with 2GB RAM and 16GB eMMC flash, and the ABX00173 SKU with 4GB RAM ...

Abstract: This work studies a magneto-optical surface plasmon resonance (MOSPR) sensor design that uses the photonic spin Hall effect (PSHE) concept, including cerium-substituted yttrium iron garnet ...

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 ...

With Christmas a little over two weeks ago, one might be scrambling to find a gift for a loved one, friend, or family member. If you’re familiar with Arduino or Raspberry Pi and have a free weekend, ...

A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables engineers to perform non-contact measurement of shaft rotation, detect the ...
