What Are Hall Effect Sensors and How Do They Work?
Briefly

Hall effect sensors offer precise inputs in various devices like keyboards and game controllers by measuring the change in voltage caused by the interaction of magnet and current.
Although Hall effect sensors fell out of favor for a time, their recent resurgence is driven by advancements in technology and the demand for better performance in peripherals.
The Hall effect's application in modern keyboards allows for enhanced responsiveness and durability, making it a valuable choice for hobbyists and gamers looking for superior performance.
The initial discovery of the Hall effect by Edwin Hall demonstrated a significant relationship between magnetic fields and electric currents, laying the foundation for numerous technological advancements.
