Arduino CT Sensor high voltage

I want to collect amp (20 to 100) data & store.

CT sensor I guess implies Current Transformer Sensor?

DC current or AC current? If AC would you like true RMS or will average responding be OK?

Once you collect the data where would you want to store it?

How many samples do you want to store?

If this is for a commercial application I would look at any of the current transducers available which cover you input range and output a proportional 0 to 5 volts DC.

You need to provide much more information about your project.


And what are you going to do with all the datas & stores?
