The humble current shunt is an excellent way to do just that. Ohm’s Law. To understand current, it’s important to understand Ohm’s Law, which defines the relationship between current ...

A quick look at the SMDs shows that the user has attached six R002 (0.002 Ohms) shunt resistors across each 12V cable. The inclusion of a USB port at the backside of the PCB means the readings are ...

Hall sensors offers several advantages over shunts and CT’s – accuracy ... but the pictures of the PCB should be enough for someone wanting to build their own version of this current sensor.
