Well, it was a pump controller, but this one might be for something else.

yep, I know, but I thought this project is still small enough to be soldered manually. i'm thinking about some improvements for the setup already, I guess then I'll do it that way. or go to some shop to make me a double layer board

BTW, there are standards for how much current your sensor can draw. I don't know it exactly, but MOSFET buffers might be a good idea.

It's an EKG machine, right? I am talking about the probes that attach to your skin.
