Maxim Integrated Products introduces the MAX9921 dual, 2-wire Hall-effect sensor interface IC. This single-chip solution supplies and monitors the current drawn by two Hall-effect sensors, filters the ...

Suited for automotive applications, the MAX9921 dual two-wire Hall-effect sensor interface IC supplies and monitors the current drawn by two Hall-effect sensors, filters the sensed-current level, and ...

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 ...

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 ...

Hall effect sensors are everywhere right now. Keyboards, game controllers, and DIY kits use them for more precise inputs. But with any newly popular device, it can be easy to immediately jump onto the ...

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 ...
