霍尔传感器（Hall Effect Sensor）是根据霍尔效应制作的一种磁场传感器，当恒定电流通过内部的霍尔半导体片时，将在垂直方向产生电位差即霍尔电压。这个霍尔电压随磁场强度的变化而变化，磁场越强，电压越高，磁场越弱，电压越低。虽然霍尔电压很小，通常 ...

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

There are plenty of PC joysticks out there, but that didn’t stop [dizekat] from building his own. Most joysticks measure position mechanically using potentiometers or encoders. Only a few high-end ...
