This paper introduces Hall-effect technology and then explores how it has been applied, in particular, differentiating between the primary types of Hall sensor ICs, and the highly differentiated range ...

Competitive gamers look for every advantage they can get, and that drive has spawned some of the zaniest gaming peripherals under the sun. There are plenty of hardware components that actually offer ...

The A139x family, released by Allegro since 2005, is a Hall-effect sensor IC family that has only 10 mW power consumption in the active mode with tri-state output and user-selectable sleep mode. A ...

A research team from Nanjing University has developed an in-situ on-device electrochemical intercalation method to manipulate the structural and electronic properties of MoS 2 thin flakes, resulting ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into 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 technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...
