Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

This application note presents some of the fundamental information about Hall-Effect sensors. It also presents the basics of magnetics, and the added value of programmable sensors and sensor interface ...

While TMR works differently, it's a similar concept to Hall effect devices. When you move a TMR joystick, it moves a magnet ...

Closed-loop motion designs in aerospace, semiconductor, automotive, military, and medical manufacturing, as well as oil-and-gas exploration and production, require repeatable and reliable measurement ...

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 ...

[Peter Jansen] is the creator of the Open Source Tricorder. He built a very small device meant to measure everything, much like the palm-sized science gadget in Star Trek. [Peter] has built an MRI ...

Researchers have invented Hall effect magnetic field sensors that are operable at high temperatures and harmful radiation conditions. The sensors will find applications in space craft and nuclear ...

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 latest reports by tipsters show that Google Pixel 7 may come with a Hall effect sensor to identify magnetic fields. This sensor is also used for flip covers. Google still hasn’t pulled back the ...

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 ...
