More and more keyboards and video game controllers employ Hall effect sensors, but what exactly is this technology? We break ...

Acceptable values of leakage current must be evaluated in this type of circuit. Switch types can be normally open (NO) or normally closed (NC). Image Credit: Fargo Controls, Inc. If the switch is a ...

current sensor IC for <5 A current sensing applications. It incorporates giant magneto-resistive (GMR) technology that is 25 times more sensitive than traditional Hall-effect sensors to sense the ...

An ATtiny25 microcontroller reads data from a couple of hall effect sensors and the neutral switch, then displays the current gear on a 7-segment display. There’s a magnet on the shifter and ...

The first video below lays the basic groundwork, with a bunch of experiments with 3-axis Hall effect sensors, specifically the Texas Instruments TMAG5273 and TMAG5170. They’re essentially the ...
