CoreConduit: Automated Garden Controller




Introduction: CoreConduit: Automated Garden Controller

About: I have a degree in Electronics Engineering and various certifications in all kinds of internet programming languages. Professionally, I have over 20 years of experience in various roles including an electron...

A garden controller helps us to manage the environment by controlling fans, heaters, lights, pumps, and notifying us when the garden needs our attention.

Step 1: Compile, Upload, and Done...

Make the modifications to the source-code as shown in the included readme file.

The controller has been programmed to help you maintain optimum growing conditions so plants with thrive. You are welcome to make changes, adjustments, tweaks, whatever you like to customize the controller to your style of gardening.

Compile the source, upload to Arduino, and the controller is ready to use provided a power source. The USB or the barrel jack are typically used to power the device.

Step 2: More Info?

More info on Hydroponics

Why doesn't the controller connect directly to the Internet?

I have also evaluated many other similar projects and found that the more complex garden controllers typically connect you to the Internet of Things. Personally, I do not want to share my garden’s data and potentially its control to just ANYONE (e.g. remote servers) unless I choose to do so. I strongly believe that the Internet of Things is a potentially dangerous path and will most certainly be exploited by those who wish to hurt honest people for their gain. The more control we give to the Internet of Things, the more we enable dependence on the internet and give away the simple freedom to live our lives in a way that we choose. I may sound a bit paranoid, and maybe I am, but hopefully I have at least convinced you to think more about what or WHO has control over your appliances. Having said that, this project is capable of connecting to the Internet. ;-)

    Interesting. Had not had much luck with hydroponics.. always problems to get bell siphon to work, So now I have done a simple set up with a container of hygroton and a pump hose all the way to the bottom. Pump in my pond, fills up the container 5 times a day and the water drains back through the pump. Goes very well. Yet, still want to make a more sophisticated system. Will look into yrs a bit deeper

    Thanks for commenting! Your setup sounds interesting as well :-) I primarily use hydroton/LECA and coco for my seedlings. I'm continuously updating the project. I've gone from humidity controller, to garden controller, to home automation, and now heading back to hydroponic garden controller.

    it is an interesting cycle. I have best results with big seeds (beans, pumpkins or cuttings (basil)). Havent found a good way to start smaller seeds in hydroponics yet (rockwool is too moist, seeds just rot away).
    All in all bad results with the bell siphon, it is just too damned picky in how and when it works. so my eb and flood is just gravitational.
    Will try gravel soon

    When growing hydroponically, I have found best results using either DWC (Deep Water Culture) or Drip Ring, which is the same except that there is a ring on top dripping water over the growing medium. DWC uses an air pump (like for fish aquariums) to keep fresh air pumped into the water. Use a 3 parts nutrient solutions such as GH Flora Series and a helping of compost tea. Do not fiddle with the pH. If you are using clean tap water with an E.C. < 100 and pH out of the tap at around 7-8 you will most likely not need to do any adjusting after you add the nutrients. Next, is ventilation, the plants need fresh air including the seedlings. A wet environment and stale air are a good combination for problems. I hope some of this helps. The results are amazing!!

    I have an Aerogarden that sprays water over the roots which worked well but anything you need for it is quite expensive. dont boter about pH at all, just feed them with water from my fishpond

    One of my ibbles in fact describes a controller for a growbox or greenhouse in which ventilation is alsocatered for

    can you please provide a link to the nRF Transceiver modules you used, and how to get them to work thanks

    If you are using soil or a combination of hydro for some plants, soil for others, then this controller will still work for you!! We could add moisture sensors for the soil, contact me if interested.

    how hard is this project ? could a beginner put it together? total cost? thanks.

    The controller without the wireless transmission is relatively simple. When coding Arduino to communicate wirelessly and adding a receiver to the mix, it gets more complicated. If you have an Arduino, you could build the controller for under $20. If you want to build this project from scratch, please let me know if you need any help.

    Beautyfull project and it is complete!
