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 ...

This post describes the preliminary results of a small Hall-Sensor module. This is widely known as KY-024 module. The KY-024 sensor module I got from an online retailer is inexpensive, and the ...

This document presents an application guide of Hall-Effect integrated circuits (ICs). It covers low-cost simplified switching, low-cost linear sensor ICs, sensitive circuits for rugged service, linear ...

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 ...

Hall effect sensors are everywhere right now. Keyboards, game controllers, and DIY kits use them for more precise inputs. But with any newly popular device, it can be easy to immediately jump onto the ...

Miri is a creative writer with a passion for gaming and animation. She started gaming way back in 1994 on the Super Nintendo and Sega Genesis and has been a console gamer ever since. She's currently a ...

While most sensors that surround us and make modern technology possible are well-known and understood, magnetic sensors used in magnetometers are often overlooked or misunderstood, even though they’re ...

The difference between Hall-effect sensors and Hall elements. Why Hall-effect sensors provide more than on and off information. How Hall-effect sensors can detect magnetic fields from an extended ...
