CT sensors - Interfacing with an Arduino

Submitted by Guest on Thu, 29/03/2012 - 22:27

Hi all,

This is my first post, so hi to everybody :-)

Under the section "Building Blocks:CT sensors - Interfacing with an Arduino" there is a very good explanation on how to calculate your different resistors.

Also on "Archive and Unsorted:Mains AC: non-invasive 3.0" there is a very nice picture of the layout.

But i can't find any schematics ? :-) As the picture is not very clear on this. I have all the components to interface with 30 CT sensors. But I have no idea which resistors has to connect to which resistors, etc ...

Any help would be greatly appreciated!

Thx in advance,
Jos

Sorry about that, the schematic files accidently got deleted. They've been restored now, luckily we had backups!

Hi Glyn,

Thank you so much man !!! You've made my weekend :-) You don't have by any change also an schematic for measuring voltage ?

This is really great stuff man !!

Thx !

Yeah i'm sorry. Now i think about it. I knew it was there :-( I just forgot about it when asking the question :)

I''m send you some pictures when my project is done :-)

Thx again mate !
