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 ...

While most sensors that surround us and make modern technology possible are well-known and understood, magnetic sensors used in magnetometers are often overlooked or misunderstood, even though they’re ...

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 ...

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 ...

Diodes' new programmable omnipolar Hall effect switch is optimised to let designers use the same contactless detection circuit in multiple applications or with different field strengths. The miniature ...
