Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

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 ...

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 ...

When an electric current passes through some materials, it generates a voltage perpendicular to the direction in which the current is flowing and of an applied magnetic field. This physical phenomenon ...

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 ...

The dial control atop Alarmo uses a magnetic Hall effect sensor for improved accuracy and durability. The dial control atop Alarmo uses a magnetic Hall effect sensor for improved accuracy and ...
