This is a really great pH kit from Atlas Scientific. All the components seem very high quality. The pH probe is very good, but is sensitive to electrical interference. Keep it away from electrical wires and pumps. It might be better to keep your bottles of pH adjuster outside the junction box, especially if you are using very strong acids and bases. If these strong solutions produce fumes, they could corrode your electrical components. I'm using not very strong pH adjusters and closed the solution in with cable glands and one way air vales. I have had no problems with this setup.

nice, did you power the sensor directly from the 5v rail of the board?
Thanks. Yes I did.
