Early in the study of electronics we are introduced to magnetism. The lines of force can be demonstrated by iron filings on a sheet of paper with a magnet underneath. In school science class, we made ...

This document presents an application guide of Hall-Effect integrated circuits (ICs). It covers low-cost simplified switching, low-cost linear sensor ICs, sensitive circuits for rugged service, linear ...

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 ...

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 ...

A single-chip solution that integrates three highly sensitive Hall elements—a samarium cobalt magnet, a pole piece and a Hall-effect IC—the ATS65OLSH is intended for digital gear-tooth sensing and ...

Construct this easy-to-make tool to detect hidden magnets and sensors inside modern appliances. You will find it ideal for repairs, experimentation, or simply for fun! Construct this easy-to-make tool ...
