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 ...

Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

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 ...

The evolution of Hall sensor-based ICs has seen a transition first from one-dimension (1D), discrete Hall sensors to highly integrated Hall encoders that contain arrays of Hall sensors on a single die ...

Here’s a guide to evaluating and using the latest generation of 3D magnetic sensors, which offer a higher-accuracy alternative to existing 1D Hall-effect sensors. Linear magnetic sensing is becoming ...
