Do you want to measure high DC current (and 0–26V) using a raspberry pi or similar, inexpensively? 10 amps? 100 amps? Maybe 500A? Enough of the cheesy salesman talk. — My solution is to ‘hack’ an INA219 current sensor by removing (desoldering) the 0.1 Ohm resistor and ‘replacing’ it with a high-current shunt. Don’t worry, it’s not very difficult. The INA219 current sensor is a ‘shunt’ itself, which works by measuring the (minute) voltage drop across the 0.1 Ohm resistor…
