EMDIN 01/02/03 and pulse output

Hi all,

I want to know my house electrical consumption and make nice graphs of it :wink:

It seems the EMDIN 01/02/03 products fit my needs…

velleman.eu/products/view/?id=411494

But it’s not very clear to me how to use the counter outputs… Do i have to power it on 12 V ? If so, how can i detect the pulse ? Someone can show me an example ?

Thx,
