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 ...

I was looking for a different dc current sensor ... in combination with an Arduino Uno is easy. Now you know the basic functionality of the INA219 module, but if you are interested in further ...

The idea is simple enough: just place a INA219 current sensor between the power supply ... Of course in this case, [Mark] knew what the target Arduino Nano was doing because he wrote the code ...
