Jan 25, 2019 To measure current you will need to have a ACS712 hall effect current sensor module. Always connect main line or positive on IP pin and IP.
.
8 820 AD values, or 410 values positive and 410 values negative.
This module uses I2C communication to transfer the voltage and current data.
I strongly recommend finding good insulated enclosure which you can use.

Pin A4 - I2C SDA.
Connect the ACS712 sensor screw terminals to the two wires you stripped in the previous step.
I have several 5V sensors, and need 3.
You may get better results with this jumper in place but be careful about your wiring if you.
If you have a thick solid steel wire then you can cut a reasonable length of that wire and can use as a shunt.
