@Yveaux thanks,
I have ACS712 for 5 and 30A but it has 66mV/A, would be complicated to use it with arduino uno :/
I will try to use a ct 5A + opamp like ina122 and try to read at least 100mA - 2.5A, after that I will read using the SCT model.

Hey,
Thanks for that info, very interesting. But I think too complicated to get it here in Brazil.
I had a new idea, will put here today or tomorrow because it depends from a answer of emonlib config.

I just got some info about this sensor...it can't read low currents due it features of construction, the best accuracy would be +- 5-50A range.
But I really need to read low currents like 100mA for example in my project :/
If I use 2 arduino pins to read 2 non invasive CT's with different ranges probably the CT used to low current will be broke when the current gets high...like 20-30A.

Hello,
I'm using the basic config to read at serial monitor the current from my loads(resistive).
The setup is an arduino UNO(Emonlib running) + SCT013-50A with classic voltage divider+capacitor 10uF.
I can see currents with good acuracy only above 1A, so its my question...
How can I read currents like 30....100mA?
Thanks in advance
Cheers
