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 ...

[Tom Stanton] has been playing Microsoft Flight Simulator a lot recently, and decided his old desktop joystick needed an upgrade. Instead of just replacing it with a newer commercial model, he built a ...
