Loading commentsThis Blog is about making a nutrient dosing system for hydroponics that is plug and play, I didnt quite get it to the full stage of plug and play with this version. But it is almost there. Because the change of nutrient strength of our systems can be modelled as a linear system with respect to nutrient delivery it should be possible to implement a very simple self tuning control system based on the system model.
Why a Self Learning system:. I made this control system with Urine as a nutrient source and because the concentration of urine can vary we need a system that can take this into account. It will also work for traditional liquid fertalizer. Although this is a self learning system we still need to choose a nutrient pump of a suitable size so the pumping interval is quite large to reduce the effect of pump priming and post pumping discharge [Fancy words for the pump acts weirdly when we first turn it on and just after we turn it off].

I recently started a new planted tank and realized how bad my lax dosing schedule was… to fix this i decided to build an arduino based dosing system.
Yes it may be overkill. I searched the web for countless hours researching how to build this project… I found lots of bits of information but no complete guides so i decided to do this write up as a step by step guide for the beginner arduino builder.
Drill some holes yo mount the motors. Paint your box if desired them mount your components. As request I snapped a pic of the underside of the board. Pingback: Arduino auto dosser - Page 3. Its generally used with the mini breadboard but i soldered directly to it to create my final product. You could do this with a breadboard or one of the blank diy boards but the protosheild give you a nice clean pre-pinned board to build onto. Can you please help with the code?
Pingback: Automated aquarium fertilizer doser. How have you found the quality of the peristaltic pumps? I have found a number of references that indicate that these low price units from China are not worth the asking price, is that your experience?
So far they have been working awesome for me. For any hobby project i would defiantly recommend them for the price….

Ryan you are entirely correct, this is a race condition waiting to happen. The delay should be shorter. Great build, I too have been looking at the Chinese peristaltic pumps. Did yours come with the internal silicone tubing or was that a separate buy. Is there any particular reason why you did not use the 12V power for Arduino but the 5V across lcv?
Arduino can be also supplied with a voltage of 12V. David James Ryan — There really is no point to that. Be sure to post back with your progress and let me know if you have any questions. I just got a arduino mega and micro in the mail. Tom — The Pumps came with a small attached chunk of silicone tube. Conveniently with a bit of work fit inside of standard airline tubing which i slid the pump tubes into. It was a bit of a battle to slide them in so its a friction fit but in the past few weeks there has been no issues.
I wanted to build it all on to the add on board. In order to accept the 12V i believe i would have had to solder to the power jack pins on the uno. I think this can be done from the Vin pin?All orders placed will be shipped out as usual, delivery times are expected to be affected due to COVID Thank you for your continued support.

Following is the original text. So, you may be wondering Basically, hydroponics is growing plants without the use of a traditional dirt medium by using a nutrient rich water solution. Those mediums used to "plant" in range from fiberglass to sand and from fired clay balls to nothing at all.
Several branches of hydroponics include aeroponics, aquaponics, etc. But WHY would I want to take all this extra time and effort to grow my plants in this "special water"? Well, hydroponically grown foods not only taste better and are more nutritional, you can change the properties of your food, monitor what goes into your food and pollute less. You can also grow more in less space. This is especially great for those people that that have limited areas in their backyard to grow in.
With the right plant selection, you can also keep pests away; a citronella plant has oils that keep away mosquitoes and other pests. Now if this wasn't enough for you to jump right in to hydroponics, listen to this: hydroponics uses 70 to 90 percent LESS water than conventional growing does.

Step 1: Gather Your Supplies To build the Hydruino, you're going to need to first gather some supplies. Step 2: Building What I ended up doing was constructing basically a "table" for the system to sit on. The weight of the water in the drain pipe makes it heavy enough for it to easily stay on without a problem. The nice thing about this is that it can be easily scaled to almost any size and all the instructions stay the same except for the actual construction of the system of course - there would be no need to change the code I don't have a digital copy of all the dimensions of the pipe if you're looking to make a replica of what I've done, but I'll try to get everything entered in within the next couple of days.
For the reservoir, you'll need to drill two holes for the float sensors - one at the very lowest your water can be and one at the top - and also a hole for the solenoid to fit in which you will glue in. Once you've constructed the frame, you'll want to wrap the entire thing in a transparent plastic, of which you'll have to cut out a couple holes for your fans.
Cut a hole in each end of the drain pipe - one is where water is pumped in from the reservoir, the other is where water drains out back in to the reservoir to be recirculated. I never got finished with the container for everything to fit into, however, I'm sure that shouldn't be a problem for most of you to figure out. I took the cardboard that my relay shield came in and am working on getting everything to fit in there, since that's a really easy way to put it all together, but you can use whatever you'd like.Iptv shutdown 2020
Step 4: Code Attached is the most current Arduino code for the project. It will be updated based on feedback given by others; I don't expect my way to always be the best way! I haven't had weeks to test it "out in the real world" so there may still be a few kinks in it.
Be sure to adjust the lux value for measuring the time for the supplemental lights Also, if you're using a different pH sensor, the calculations may need to be changed to fit that particular one.
Big thanks to BillieBricks for working out a lot of the code. You've successfully hopefully! You're now able to grow your plants in a smaller area while also using less water.
Remember that you'll have to keep track of how often to add nutrient mixture. Please feel free to leave feedback, especially on the code, as there is always room for improvement and it will only help everyone! Also, please vote for me in the Microcontroller Contest! It would be amazing to have any of those prizes that they're giving out!The pH is one of the most important variables to control in hydroponic culture as it plays a key role in the availability of different ions and their absorption dynamics.
Although most growers control pH manually it is often desirable to implement automatic pH control so that you can ensure that your solution always stays within an optimum range. Do test your pH meter frequently with a buffer solution. This means that testing your pH meter with a buffer solution often — every week is ideal — is necessary in order to ensure that you are getting accurate readings.
If the reading is not accurate you can then recalibrate the meter. Do recondition your pH meter every month. If you do this your electrode will be happier and you will need to calibrate less frequently. If an electrode is covered in biofilm the putting it in a hot bleach solution for half an hour before the buffer immersion is also necessary.
Do use electrodes designed for constant immersion. Regular pH electrodes — including those sold with some automated pH controllers — are not meant to be immersed the whole time and therefore get damaged and lose calibration much more quickly when used in this manner. To get best results use pH electrodes that are fabricated with long term immersion in mind. I wrote a blog post about these electrodes and why they are different than traditional pH electrodes.
Do place your electrode as far as possible from your pH changing inputs. Placing the probe close to the inputs will cause very erratic changes in the pH that do not really reflect the effect of the addition across the entire reservoir. Do have addition limits in your controllers. Allowing a pH controller to add as much substance as needed to correct the pH can be a very bad thing to do. This is because several things can go wrong — pH probe losing calibration, controller getting damaged, electrical noise etc- that can cause unnecessary levels of addition that can kill an entire crop.
Always have controllers where maximum additions per unit of time can be specified so that the possibility of this happening is minimized. Although single probe controllers are the most common they can also be the most dangerous. A pH probe can get damaged, it can lose calibration or it can give erratic readings due to other reasons for example electrical interference from other things in the reservoir.Pages:  2 3.
I would like 3 pumps one for each PH up, down, and nutrients. The system contains Litres with a L resevoir. The PH pumps probably need a minimal flow rate. The nutrient pump will need to be big enough for a full dosing L5ml of nutrients per litre of water, but still able to make smaller frequent hourley-daily doses. Any advice please? Those ebay pumps may not be ideal for metering the addition of chemicals. Google forum search: Use Google Search box in upper right side of this page.

Quote from: syphex on Sep 26,am. Quote from: Chagrin on Sep 26,am. I have found that those cheap ebay peri pumps work well The silicone tubing that runs through the pump head had a tendency to wear out after months.
The wear on the brushes is exacerbated by inductive arcing caused by frequent starts and stops the stops really.
The flyback diode shunts the energy away from sensitive digital logic circuitry and back into the motor windings. It protects the circuitry not the motor. For a prototype, a cheap brushed motor works ok but wears out quickly. For a long term solution you should look into a stepper or higher quality motor.Arduino EC, PH, PPM, Water temperature and height controller V2
You get what you pay for basically. The voltage depends on what is most convenient or whatever power source you are most likely to use. In my opinion, 12volts switchers are pretty cheap and common. Just depends on your situation. Test equipment, replica and original sci fi props and costume pieces, and whatever else I feel like at the time. I have an Ultimaker and a 3D engraver.Jira cloud find custom field id
