Current Sensor Module:
ACS712 Module can be used in motor control, switched-mode power supplies, load detection and management,and overcurrent fault protection ect.
Voltage Sensor Module:
This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, Arduino analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because Arduino AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum
Package includes:
1pcs x 5A ACS712 Current Sensor Module,
1pcs x 20A, ACS712 Current Sensor Module
1pcs x 30A,ACS712 Current Sensor Module,
1pcs x Voltage Sensor Module DC0-25V Voltage Tester Terminal Sensor

There is no way to use those for 30Amp, too small connectors and PCB. It is okay for 5A-10Amp I would not go higher.

It was what I wanted and it did get the job done.

simple design and execution as parts are Surface mount and difficult to bread boardnice selection of current ratings to choose from.

So far I have tested the 5A version and the 25 volt voltage divider. Both work great.

Terminals do not fit larger gauge wire. This is important for 20-30A modules because it is unsafe to run that much current through small gauge wires

I did not notice a way to tell which module is which. I just picked one, plugged it into the circuit and it works.
