I am using the circuit and probe for a hydroponics system. I was wondering if you found an alternative that works better for you? I’d be interested in exploring other options as they become available. Always good to know what is out there!

Do you know which lapse camera you are using?
These are great references. Your “higher end” does not reference the Atlas Scientific (also it is $20 less expensive). Have you found your recommendation to be better - or is your choice based on price? Ability to buy on eBay (i.e.: less expensive).
I’m glad you tooted! There are great projects and insights that you share. Parden if this is on the sight - which pH probs did you use? Are there ones you’d recommend over others?
I played around (Atlas Scientific) pH sensor kit w/ my Arduino this summer. I really appreciate the simplicity you brought to calibration and then pH reading. Great job!
The challenge I have is the pH sensor costs over $100. I want to make many to stick on each of my sensor nodes. Each sensor node is attached to a hydroponic system. My intent is to grow a lot of vegetables in my house using multiple hydroponics systems and then perhaps if all goes well, make kits for others.
Is there any thought/idea to getting a pH sensor cost to sub-$10? Why is it I can buy a “good enough” pH hand held meter for sub-$10. I know it won’t be as scientifically accurate, but that is perfectly ok.
great video and thanks (to anyone!) for recommendations.
No public wish lists :(
