I got a couple of INA 219 modules from an online seller overseas. I was looking for a different dc current sensor module to start a small battery charger project, so I welcomed them. The INA219 based ...

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 ...

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 ...

Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...
