View Full Version : pH probe recomendations for Arduino
I picked up my Arduino board yesterday for my Reef Controller Build.
What I am looking for are recommendations for a pH probe to use with this.
Any suggestions for a reasonably priced one would sure be helpful.

I have ordered the ph probe from BRS, it was reasonably priced, Haven't hooked it up yet since i am waiting for another IC chip for the PH circuit.

What are you guys using between the probe and arduino? I figured in the interest of accuracy I'd buy an interface board instead of making my own circuit. I ended up with one of these (http://sparkyswidgets.com/Products/Store/Details/tabid/81/ProductID/4/Default.aspx) due to the soldered-on BNC connector, mounting holes, and 4 different methods of output. I was a little wary of the website since it seems like a very small operation and there is hardly a peep on google about it, but hey it's $30. I only ordered last night, though, so we'll see. Second choice was this one (http://atlas-scientific.com/index.php/store#ecwid:category=1812540&mode=product&product=7766615) from Atlas Scientific.

I got my probe from BRS the other day and I prototyped the circuit using the schematics posted on practical maker site. Unfurently I don't have any calibration packets so i cannot calibrate it at the moment.
It might be actually simpler to get one of these stamps, i was thinking to purchase AS EC kit, each seems to be priced fairly.... However i need to move in couple of week and i need money to pay the movers lol

This is the only way to go for the stamps imho: http://atlas-scientific.com/index.php/stamps.html
