I did a a pH ec and water temp controller that last couple of days. Pretty easy all in all and here is a few pics. All I got to do is make up some nutrient by weighing out said quantities, mixing with ro water, and measuring into my 1000ml volumetric flask. Way better way cheaper. I run 40 gallon reservoir changes every week for six months straight for 200 Dollars in compounded soluble elements. I got a mix that has the whole core, bloom , grow, balance and cleanse that I make concentrate mix into gallon jugs. Anyone wanna talk Arduino, c++, Python or nutrient amounts they can do themselves. I am computer tech\ computer sciences background. I got some seeds I been dying to plant so I've been on crunch mode doing many projects to hit this deadline of Halloween. I did a total upgrade on my equipment and controllers.

This is really neat. I love the idea of being able to automatically control ph.
How has it been working so far?

works really well and couldnt ask for a better ph ec and temp senors. It is really easy and there is so much info out there on making your own controller. They are cheaper than buying a bluelab or a name brand. When I started messing around with arduinos I never had worked with them years ago and thats how I learned. I recommend jumping into it and learning about them. You can do just about anything you desire with them.

So have you found it's able to keep the pH stable? Does it just add a little tiny bit of pH up or pH down at a time?
I've wanted to program one for tent controls. I work in a lab and these are used all of the time. The elect. Engineers are amazing at what they can do.
I have all of the sensors and things I need, just haven't made it there yet.
I also wanted to make a lap counter for my kid in his bike. Wanted to add lights and noises for the winning lap going around in our yard. These really are a cool thing, I just don't get enough time in the day as we all don't....

Do these things work by just adding PH Down or PH Up when It notices the tank needs it?
Its pretty easy.It sounds like it is so complicated but it really isnt. Anything you want to learn to do is online especially arduino and esp 32. All it is taking code and pasting it, if it works yea, if not try again. Sometime it goes smooth, sometimes it doesnt. Last build was about eight hrs coding. I mean you can code it so it reads but if you want wifi, data, a laptop as a network you need to take a bit more time. Depending upon what os you laptop uses is what code you use for networks. arduino are c++ code. My hp laptop is in python. Linux is dif than windows. Blah blah right?I've wanted to program one for tent controls. I work in a lab and these are used all of the time. The elect. Engineers are amazing at what they can do.

Jump into it start doing something easy. Its pretty addicting when you get going.
If that is how you code it. A easy answer for you anything you want automated a arduino can handle. Its just writing code to take varibles, addion sub, mult, div, math in words sort of. Yes you can have one that alerts your phone when temps are...... ph is,,,,,, ec is......... you can make them run a perstalic pump using a stepper motor. Easy man.Do these things work by just adding PH Down or PH Up when It notices the tank needs it?
You can make it anyway you want I'd say. Infinite sensors available and only limited by imagination/ coding abilities. I don't know how to program them.... I usually have the engineers make control boxes for me for my tests.
I don't think I should post the video but I just ran a test to capture one shot of powder from a pump out of basically a stream of powder. I just had it trigger off a solenoid and then I could control how many milliseconds it held a piston open for. I connected the piston to a tube and it shifted to a filter cup under vacuum to hold the powder to then measure the shots. Was a fun test.
Just think of what you want to happen at any event and you can do it. Low pH, add drops till xxx is met. Hight pH add till xxx.

Thats cool man and thats how ya get better. I think the stuff is super cool bc it is pretty much unlimited, well limited to your imagination. Code isnt hard. You just start by writing out regular talk on what you want to do, then write a simple code and go from there. You can get help everywhere git hub, root master. People just like to help out.
