Earlier, we designed a smart energy meter that used a current sensor to measure current. In that version, we manually set the ...

It’s always interesting to see how scientists and engineers have exploited—in the positive sense of the word—somewhat obscure, fundamental physics principles to create innovative sensors. For example, ...

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 ...

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, ...

Fluxgate current sensors have emerged as a robust technology for the measurement of both alternating and direct currents, harnessing the non-linear magnetic characteristics of ferromagnetic materials.

The battery packs in electric vehicles (EVs) are only as safe and effective as the battery-management system (BMS) watching over it. The BMS plays a pivotal role in the EV, monitoring the voltages in ...

Accuracy, bandwidth, speed, and other performance metrics for Allegro’s latest magnetic current-sensor IC. The importance of current sensing for demanding control loops that dominate EVs and ...
