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 evolution of Hall sensor-based ICs has seen a transition first from one-dimension (1D), discrete Hall sensors to highly integrated Hall encoders that contain arrays of Hall sensors on a single die ...
