Thank you for watching my video! Please comment with where you are from so that I can say hi. If you want to you are also welcome to tell me about your system, or what you plan.
Sir firstly i wanted to say thank you for developing this amazing code on Calibration of Ph and TDS, i am using that code of yours and fulfilling my requirements but now sir there is an ISSUE i am facing and that is when i calibrate the sensors with smaller values of PH and TDS like (under 1000ppm and Ph around 7-8) then it will only shows the correct values of ph and TDS under that values only i.e. When the system is calibrated at like 800ppm and the system is fed with like 4000ppm then it only shows 2500 ppm . sir i will be very thankful to you if you can provide me yours insights on this issue.
thank you in advance, I made it and it can work according to the code. The problem that arises is that you cannot monitor the nutrition value in the reservoir at that time. so it would be nice to add an oled monitor and a link to thingspeak
after years of growing hydroponically I have found it easier to have 2 tanks, one for the system and a refill tank. The refill tank has the nutrient which is at correct EC and PH. once the system has been cycled the refill tank will fill the main reservoir back to it's original level. I use this system on a flood and drain system. Only need to test PH once a week and compensate the PH level in refill tank to keep things perfect.
A perfect PH doesnt affect the elemental content of the nutrient. Running a nutrient solution through a system alters it elemental balance. Elemental unbalance is the reason why folks have to dump the reservoir periodically.
Hello and thanks Pierre! I appreciate all your help. I am having difficulties because I need a code that can activate 2 dosing pumps before taking ppm readings. Any suggestions?
Thank for the Video. What if we have 2 parts of the nutrients? Say Solution A and Solution B. In such case, do we on the pumps both together? or 1 pump first then the 2nd? Also how to measure that both solutions were pump with the correct amount? thank you.
How do you control the nutrient mix when you use several different parts such as general hydroponics nutrients?. Just how do you dose each individual part? I don't like the Idea of putting a preassembled mix into my water. I hope I'm getting this across.
Would it be possible for you to do a code for Thingspeak that has everything together? I'd love EC dosing, PH dosing, temp all auto. I just cant wrap my head around the code. Hope you can help, thank you.
In your video , you used 2-Channel relay module, and in that while ppm is low, will two channel relay (two motors) turned on simultaneously? Or only one will do? Can we configure that to work with only 1-Channel? Please help
The EC measurement range is very close, so when it is calibrated with 1.413, it cannot read 12.88 correctly, and when it is calibrated with 12.88, it cannot read 1.413 correctly.
If you are interested, I can do a short mini course on it. Adding a display and PPM set function. It will take les than a week to compile the course. The course will contain all the information that you need as well as the code. Enrolment fee is $12. Let me know if you are interested.
Dear sir best explanation, i made pH meter with arduino i hv 1 problem if i put pH probe direct into my aquarium value start variation but when i put probe in a small bowl water value become stable, plz can u guide me what's issue.
Dear Mr.Pierre, Is it compulsory that we should use peristaltic pumps for dosing? Can't we use normal aquarium water pumps for doing? What's the diff b/w dosing pump and normal water pump? Will it be efficient?
A peristaltic pump delivers an accurate volume per revolution andf can produce a lot more pressure which is useful for long runs of small bore tube. The flowrate of a normal water pump will change depending on how much tube is attached, how how high the liquid is lifted. Something as small as a change in the depth of liquid in the reservoir will alter the flowrate of the pump. If funds are tight there are a few vids on youtube related to 3d printed peristaltic pumps.
We have dosing pumps in different sies, i.e, 1mm ID x 3mm OD (2-17ml/min) 2mm ID x 4mm OD (5-40ml/min) 3mm ID x 5mm OD (19-100ml/min) Which one i should choose? and which one is used in this video?

hi there, thank you for sharing this project.. only we have followed the steps and for some reason the relay is continuously active even when placing the probe in a solution with a higher than the set value in the sketch..
There can be a few things that is not correct on your side. Very difficult for me to give blanket advice. Please go thru the steps carefully again. Hope you sort it out. Pierre
@@doitwithpierre210 Hi there sure thanks for reply... have gone through breadboard wiring several times.. after calibration the probe is working how it should.. opened a new sketch and pasted code 8 with dosing option, re-calibrated probe checked serial monitor probe is working with different solutions and giving readings, though the relay is powering on continuously. When the probe is out of the solution(s) the relay cycles as per settings i.e. on off on off however, once probe is placed into a solution regardless of being under or over the set ppm level it remains on constantly... i.e. without delay or stop time.. could only suspect the code has an error maybe.. wounder whether you could send sketch 8 again without pdf ??? maybe something is moving on sketch lines or missing??

Thank you!
This is actually a good method instead of using a weight to measure how much nutrients is left in the cup

A refill tank works well. Especially in small systems.

Isn't easer to have a bigger tank?

Thanks for the build! I use an A & B nutrient solution and this build is way above my head. Any chance you would sell me a ready made set up?
It is easier than you think. You can use the Arduino for many other projects as well. Check out my Arduino course if you like.

nice video, simple and full of information... sir i have a doubt.. should there be a wire from 10k to grnd? or i misunderstood?
Yes, one side to ground.

Only one of the relays on the module is used. You can later switch something else with the other relay, or just use a one relay module.
The EC measurement range is very close, so when it is calibrated with 1.413, it cannot read 12.88 correctly, and when it is calibrated with 12.88, it cannot read 1.413 correctly.
Dear Sir can we set "Set_ppm " with button or rotary encoder ? So we can up and down Set_ppm by manual. Thanks
You can do it but you will have to modify the code.

You need a dosing pump. If you are innovative you may be able to use different pumps.
@@doitwithpierre210 Can you recommend suitable alternatives? The peristaltic pumps are sometimes cost prohibitive.
@@john_blues Any pump that can accurately supply the nutrient solution and not corrode can be given a try. You will have to experiment.

Which one i should choose? and which one is used in this video?
Choose one that fits your system. None were used in this video. With the described system you can switch any pump.

Can we use normal aqauarium pumps for dosing ? Like this one in the link avrobotics.in/products/dc6-12v-mini-aquarium-water-pump-r385
You can experiment with different pumps but peristaltic pumps work best.
change per dose arent very practical, as for experiment its gradually change too. why dont do it in on/off system :/
Good point. This is a basic setup for anyone to get started. It can be customized as you like.
