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 ...

While TMR works differently, it's a similar concept to Hall effect devices. When you move a TMR joystick, it moves a magnet in the vicinity of the sensor. So far, it's the same, right? Except with TMR ...

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 ...

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 ...

Insight on Diodes Inc.’s first automotive-compliant 3D linear Hall-effect sensor. How it allows for reliable and high-precision contactless rotary motion and proximity detection. Application targets ...

Diodes’ AH4930Q sensor detects magnetic fields along the X, Y, and Z axes for contactless rotary motion and proximity sensing. As the company’s first automotive-compliant 3D linear Hall effect sensor, ...

After improving hard drives, tunneling magnetoresistance technology could put an end to joystick drift. After improving hard drives, tunneling magnetoresistance technology could put an end to ...
