How a Mouse Knows You're Scrolling? Part 1

Optical rotary encoders and magnetic rotary position sensors are both used to measure rotational position, but they operate on different principles. Optical encoders use a light source and a photodetector to read patterns on a rotating disc, offering high resolution and accuracy—ideal for clean, controlled environments. Magnetic sensors detect changes in magnetic fields using magneto-resistive elements, and while they also offer excellent precision, they shine in harsher conditions like dust, oil, or vibration. The choice often comes down to environmental demands and mechanical design needs. #scroll #magnetic #infraredlight #brancheducation
