We wanted to give it a try to grow vegetables, and do this inside our wintergarden, therefore I decided to build a raised garden bed on wheels. But since I do not have green fingers I wanted to make sure this build can take over the periodic water irrigation tasks by itself. I want to use a self-built arduino-controlled irrigation system with a big water tank, a pump and a perl hose. The arduino will trigger twice a day the irrigation loop.
I attached an ultrasonic water level sensor to the cover of the tank to know when the water tank is full (indicated by a green light) and empty (indicated by a red light).
I added to the task list the possibility to start and stop an irrigation cycle manually by adding buttons and see whenever the irrigation is running (indicated by a blue light). A small display gives me feedback about watertank level and remaining irrigation time while running.
Then I added some moisture sensors to control soil moisture and trigger an extra irrigation
run when too dry. Additionally I added a temperature and a humidity sensor to have the complete data set.

All this is controlled by an arduino that reports temperature, humidity, soil moisture from four moisture sensors,
tank level and irrigation activity to the cloud so I can monitor it from anywhere.
Irrigation can also be started from anywhere.

I also added a foldable table to the design of the garden bed to have some work space.

Now, only covid helds us back from going on vacations.

The irrigation loop is better visible in this picture. I added some pvc tubing inserts into the holes to increase the livetime of these removable dividing sections.

The manual user interface.


The widget on the mobile.


And accessing the data graphs by an app on the mobile.

WOW! What a setup! I would not have the patience to build and test that. Awesome job, we expect to see the producing plants at a later date. LOL

Looks amazingly complicated to me but intriguing. I don’t know anything about Arduino controllers. So how hard is this to build Not including the woodwork? Where did you get the sensors? What is learning curve on the controller? Costs? Interested in more details. Thanks.

It is really surprising how easy these arduinos are to work with. A motivating starting device from arduino is the “Wemos D1 mini” with its various shields you can stack on top of the arduino. some soldering is necessary to attach the legs to the board. A great starting point to get some ideas and see how it works are the tutorial videos from https://randomnerdtutorials.com/

Thank you, Petey, don’t know who she is, but will google her for better understanding your post.

I love it. That is the best way to have a garden…where you don’t have to kneel or stoop over…and it self waters the plants!!!!!!!!!!!!! Excellent build..a lot of thought went into that project and you did a very fine job on it!!

Cheers, Jim

I checked the learning site randomnerdtutorials mentioned above on how to learn arduino to control things. Honestly, I was so confused so fast that I didn’t know where to begin. The simple irrigation system we use is a battery operated timer/valve that screws into any hose or faucet.

If you added grow lights to the control system, you’d have the perfect garden bed for growing pot in your basement or attic. But hey, in California, its legal so that would take some of the forbidden thrill away.

This is growing way better than I thought! I was one week off and came back thinking that some of the plants surely had suffered and the surprise was huge to see the plants healthier than before I left.
