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 ...

Vertical Hall sensors, integrated within standard CMOS processes, have emerged as versatile components for magnetic field measurements in a range of industrial and consumer applications. These devices ...

Mechanical keyboard fans have seen huge innovation lately, particularly with magnetic switches in Hall Effect keyboards. Now, ...

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 ...

Melexis Technologies NV has followed up the success of its initial MLX92242 Hall effect switch/latch IC, which offers end-of-line (EOL) programmability and support for 2-wire operation, with a further ...

Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

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 ...

We’re used to thinking of limit switches as a mechanical device that cuts the motor connection before physical damage can occur. [Anthony] decided to try a different route with this project. He built ...
