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 ...

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

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 ...

I have a pile of different generic electric bike throttles purchased from several online sellers. They all arrived about a week ago. I have a goal of using them to make the basic model of an electric ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Allegro MicroSystems, LLC rolled out a new family of contactless, Hall-effect based magnetic sensor ICs for high speed motor position sensing applications. Allegro’s dual-die A1331 and A1334 angle ...
