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 ...

Isolation in this case, is from the mains, and it transpires that finding something that will do the job safely is tricky. Three isolated Hall-based current sensing modules are easy to obtain, as far ...
