I actually got one a year ago, cut it up thinking I could reverse engineer it, but the project never got of the ground.Still got the board, without microcontroller. If you need pic without, I can post one.If I understand it right, it has a pin for every "line" on the 8 display, if you connect them to your arduino you could get a reading like that.Sorry for my EnglishHope this helps:
oh , sounds like one big job to figure this out, is there any logic way to do it?
Oh i had nearly given up, the PH meter is made by a chinese firm (kelilong), the component looks like the one they hawe used in this board: http://www.sparkyswidgets.com/product/leophi/
