I am looking for suggestion on how to best measure current consumption of mains with my arduino(230V, I'd say 30-50A max).e.g a dehumidifier .
I would like to buy ideally a module I can interface with and read the output, something like this, but that doesn't cost more than 30 dollars top.
Anyone is aware of any module that can be easily interfaced with arduino? or how can it be easily achieved?
Appreciate your help!
