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 ...

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, ...

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, in all its forms, is fundamental to so many applications. It invariably involves a material that acts as a transducer, to convert one property to another. In electronics, the sensing element ...
