The Allegro ACS716 current sensor provides economical and precise means for current sensing applications in industrial, commercial, and communications systems. The device is offered in a small ...

The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Can current-sensor ICs win out against the shunt resistor and other passive components? Check out some of the latest offerings on the market in this Products of the Week gallery. For any electronic ...

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 ...

The ACS37200 isolated current sensor from Allegro MicroSystems is a galvanically isolated current-sensing IC designed for ...

Usually, when you need to sense something in a project, the answers are straightforward. Want to sense air temperature? There’s a sensor for that. Particulate content in the air? There’s a sensor for ...
