Hi,
I have the following requirement:
Identify/measure the voltage values in the 3 phase lines using a Arduino Uno microcontroller.
I know that I cannot feed 230v to the microcontroller. The input voltage to it is 0 to 5v.
Can anyone suggest is there a existing module that takes in 250V and gives out 0 to 5v proportional analog voltage?
So that I can feed that analog voltage to the microcontroller and calculate back actual voltage using a formula?
I have also placed my question in the diagram in the attachment.
Thanks in advance!!
