DFRobot were nice enough to send me one of their pH pro MCU probes [Longer lasting] but this tutorial and code will work for any analog pH MCU meter [ebay special etc] these are coming down in price rapidly but I recommend calibrating often. I'm ...
It has been two weeks since my last post. A lot has happened with the project since then, but even more has happened in my personal life. I have been too busy to post because my son was born 11/9! He surprised us by coming about a month early, but I ...
Sometimes we want to store data on the arduino that will survive a reset, calibration settings and set points are an example of this. EEPROM is a non volatile memory on the arduino that we can write values to and read in the setup loop to keep the va...
This Blog will cover how to measure pH in your aquaponics/hydroponics system, later we will be using this reading to control the pH. Take a look at the blog below to see why PH is an important factor and why we need to be controlling it. Bl...
This Blog is about sending your data to the "cloud", this means we will be sending our data logs onto someone else's server running at some place. SparkFun have been nice enough to host a free database for sending logs to: Her...
For People running a headless set-up like myself it can be very useful to turn the arduino and ethernet shield into a basic web server. This is a very basic blog heavily based on the work of other people [see the top of the code for credits]&nbs...
Long term data logging from our projects is a great when it comes to developing the system further, from the data we can fine tune our grow bed ratio's work on controlling any variables that vary more than we would like and attribute the causes of a ...
The main problem with the probes in the soil is the degradation from electrolysis of the probe material, you can either buy a capacitive probe or a gold plated resistive probe but maybe we can use a few tricks in the software to prolong the probe lif...
So far we have covered aquaponics/Hydroponics automation and control, we also have a soil based system to use as a comparison.It is best if we automate this system too, Just so we have an accurate measurement of water used and the moisture level of t...
Hi guys,Recently I got to design a project which was farming oriented. Due to lack of time for regular updates, I did not apply for the vertical farming challenge but I did get a lot of inspiration from the posts and have come up with a solution that...
Sorry I been away guys. So much has been going on with my new job, moving to a different state, life has been very hectic. It doesn't mean I have not been working on the project, but I just haven't been able to collect my notes to write you guys blog...
Hi vertical farmers, The purpose of this post is to share our source code.The source code can be accessed through this repository.The repository is composed by the following modules:Grow Sharp Base controller (firmware running on one EZR32WG boa...
Well I learned a little bit of python and have cleaned the basic code up ready for evolving it into the ultimate plug and play self feeding system. This is the basic code, we will be developing it to identify fish breed, size and optimise feedin...
We will be using opencv to fully automate the feeding of fish, to do this we need to be able to:>Identify breed of fish>identify Size of fish>Track the food consumption at feed time OpenCv can perform all of these functions using a raps...
Hi vertical farmers, In the previous post we presented the first experiments with our vision system. In this post we will review our progress. At the beginning we proposed to do a modular automated hydroponic system with all year production...
Hi vertical farmers, In the previous post we did a walkthrough our web application for supervision and control. In this post we will show our first experiments with the vision system introduced on Post 7 - Vision System. Just to refresh the...
What is pHThis is a subject my high school teacher quickly covered as:"It is a logarithmic representation of the concentration of H+ ionsThe pH scale measures how acidic or basic a substance ispH==7 neutralpH<7 alkaline [basic]pH>7&...
It has been a busy week with Halloween and some unforeseen breakdowns on the farm. we will be catching up on a slow week today. CO2 is an important factor in plant growth, in some instances sealed grow rooms run at a artificiality elevated CO2 c...
Hi vertical farmers, In the previous post we talked about the germination of our seeds. In this post we will show our web application for supervision and control which development started on Post 8 – Database. In the following video we make...
Hi vertical farmers, In the previous post we showed our Automatic Nutrient Dispenser functioning properly and how we controlled it. In this post we will talk about the germination of our seeds. GerminationWe followed the germination pr...
Tonight I wired in the Arduino to the control panel and I'm happy to say that most of it worked right away. I had miswired the HC-SR04 ultrasonic sensor, but once I finished that, I started to calibrate the system. I started with calibrating the ...
So the biggest issue I have with this project is my day job, which continues to result in my planned weekends and weeknights being spent working on writing code and test cases. I know, there's no whining! At any rate, the seeds have offici...
Last night, 10/20 I planted my seeds for this challenge. I began the process on 10/19 by soaking 65 1.5” rockwool cubes in water with a ph of 6.0. I usually soak them for at least 12 hours. This accomplishes two things. For one, it helps lower the ph...
