The INA3221 is a 3 channel voltage and current sensor, which work with I2C. The INA3221 is a 3 channel measuring device to measure voltage. Derived from that voltage and a given shunt, the library ...

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 ...
