if you don't need instantaneous current sensing but can react within 10 or 20 milliseconds..... you can 'filter' the output to DC with the circuit I posted and constantly take a few samples and scale...

can't tell, the picture is too blurry to read properly but i see no reference to a resistor mentioned it the bits i can read
post a link to data sheet
edit
ps, found this so no resistance...
Does this mean there is no resistance inside the sensor?

Oh, I get it now, the "plotter".
I just need to monitor a current level that will trigger a relay.
I do have ACS712 but the problem is, the current has to pass inside (though) the component...

the output is intended to be plotted in the freely available easy to use arduino plotter, the average human will have nil chance of interpreting the data with such a small number of samples. if your...

you cannot use a current transformer that way without a burden resistor.
by voltage sensor do you mean ACS712 or similar ?
if so that circuit is incorrect, typical use
