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 ...

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 ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...

The A139x family, released by Allegro since 2005, is a Hall-effect sensor IC family that has only 10 mW power consumption in the active mode with tri-state output and user-selectable sleep mode. A ...

Miri is a creative writer with a passion for gaming and animation. She started gaming way back in 1994 on the Super Nintendo and Sega Genesis and has been a console gamer ever since. She's currently a ...

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 ...

Many analog sensors today are designed to operate from a single power rail but produce output signal centered around approximately half of power supply voltage, linear hall effect sensors and MEMS ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

Melexis has brought out a linear Hall-effect sensor that draws less than 5 µA at 100 Hz and integrates digital filters for enhanced performance. Its flexible architecture is available in multiple ...

DUBLIN--(BUSINESS WIRE)--The "Global Current and Voltage Sensors Market (2024 Edition): Analysis By Technology Type (Hall Effect Technology, FluxGate Technology, Fiber Optic Technology, Others), By ...

Endgame Gear is best known for making gaming mice, but it's made a welcome foray into gaming keyboards with the excellent Endgame Gear KB65HE. This plain-looking, but high-performing keyboard is the ...
