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 ...

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 ...

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 ...

This document is intended to explain how the Thermal Compensation of the MLX90251 works and how it can be used in order to evaluate the TC of a complete system. In the first section of this document, ...

Allegro’s ACS37200 200-A Hall current sensor slashes power dissipation with its 50-µΩ shunt, offering 1,400 V of isolation in ...

Graphene-based Hall sensors represent a significant advancement in magnetic field measurement by harnessing the exceptional electrical and mechanical properties of graphene. Owing to its atomically ...
