Hello,
I have a Coilcraft current transformer which give me 10 to 50 mv AC for 1 to 5 Amps .
I need to convert the output to a digital 1 or 0, current through, no current
0 = no current
1 = current
In this case if the current transformer give me anything over 10 mv i must get an 1. I mean by 1 the +5vdc to feed to a microprocessor input.
I do not know anything about operational amplifiers, comparators, and the rest.
I would like if somebody have a schematic with parts and value, that i can put it in a breadboard and test it.
Thank you
Ion

Hi.

You doesn't make it clear if you want this device to be µpc only or allow use of analog components. I assume the frequency is 50 og 60 Hz for your task.
