PH Sensor and probe kit - $127.99Links? Curious about the probe manufacturer
EC Sensor and probe kit - $191.99
These are some sensors that I found that said they were lab grade which is why they are so expensive, I have not done too much looking around. But I figured if I bought one at a time and added them as I could afford them, that would set up a killer monitoring system for me.
Just like everything else in my build, I would rather take the extra time and spend a little extra money for a better product. If I could get these lab grade sensors monitoring my system, I would be able to use them until the parts went bad. So 5-8 years from now, I could still be monitoring and logging temp/humidity/res temp/res ph/res EC.
Even if I expanded my hydro setup to multiple tubs, I would be able to throw all of this into my control tub and still be able to use all of my equipment.
Honestly I am using a TDS meter right now, I have really been looking for a better way to measure nute strength. This is why the EC sensor has me intrigued, it is expensive, but once I have it I will have very accurate testing tools for years to come. I figured since I have the arduino up and running I would only buy sensors in the future, no more hand meters or anything.
I am worried about doing anything on "the cloud" too! I def think no matter what option I choose I am going to just set up a server on my LAN and have the computer doing all of my leg work, and then be able to view it from my phone/laptop while at home. As long as it logs into a graph, I guess I can check it all when I get home and not have that connectivity away from home.
