Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

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 ...

Development kits from Melexis come with a variety of Hall-effect current sensors for testing different magnetic configurations. One kit allows engineers to experiment with arrangements that employ ...

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 ...

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 ...

Allegro has added magneto-resistive sensors to its Hall-based range of current and magnetic field devices, for high-sensitivity high-bandwidth applications. The first product is a 5A 1MHz isolated ...

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 ...
