Hi, Can you provide more information to have an LCD screen out the action, pump on and pump off

Hi what software is this?

Thanks for sharing you will be cited in any of applications started . Mouhib

Thank you so much. loved the liters instead of gallons. helps us South africans understand better

You should continue.

A little stroke of genious! Thanks

How difficult would it be to have multiple spray cycles based on time of day? Example 2s on/10 min off from 5am to 5pm and 2s on/20min off from 5pm to 5am.

Pierre this is fantastic - saved me many hours of research :))

Very well explained, Thank you so much ❤

Thanks Sir❤

hi i want to appropriate this for esp32, anyone managed to crack the code?

Error. Compilation error expected unqualified -id before token

Can you please tell me how to connect pump and pls show which wires should connected to Arduino

Hey Pierre, wonderful video, I was just curious about how you were able to calculate the EC Electrical Conductivity, I was under the assumption you calculated it from the resistance of the water and the calibrated cell constant. But in the code you used "EC =CalibrationEC*(1+(Temp_Coef*(Temperature_end-25.0)));" is it correct to assume that here you used a relationship between EC and temperature to find the EC? if yes, is there a way to directly calculate the EC independent of temperature? I really liked this video and I hope you will continue to post great content! Looking forward for your reply

I’ve been trying to do something like this to build a simple darkroom timer. Basically, set a time in seconds on a display, then pass power during the countdown, then turn off when the countdown ends. Is that something I could do as a beginner?

Thanks for sharing

Hi, can't find the code😢

For lettuce what is the best ppm

On the diagram you show above the code (in the code files pdf) for this project, you have a diagram "typo". The vcc of the relay switch is plugged into the ground bank of the breadboard, instead of the 5v bank. THANK YOU!!!

This seems to be what I need to setup my pumps, but you have this other video "Pump timer- Arduino 9 (iAVs, aquaponics and hydroponics)" that has a different kind of code. I understand the differences, but I want to know if there is some advantage to use the "Pump timer" code of the other video vs the "Simple on/off" code in this video. Maybe there is some advantage with the other code that I am not seeing? THANK YOU!!!

Would there be any changes running this on a 3.3v system with a NodeMCU?

Hi.Pierre, every time I tried to upload the sketch an error pops, it's said; compilation error; 'pump_ con' was not declared in this scope if you know why this shows,please let me know, an sorry for my spelling.

Thank you, Pierre! Love from California!

Very good information, thank you.

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.

Sir can you share circuit diagram of Hydroponic system? (Consisting of Ph, EC, Relay modules, Temperature sensor, dosing pump etc in one circuit diagram)

Great video and thank you very much. Excited to go to the store tomorrow to get what i need. One question i have is have you seen this work with a ph sensor? Some people say that i need to turn on sensor off and the other on because they are effecting each other. Wil that be what i have to do in this case also? I can believe the ppm meter i got on amazon only goes to 1000 ppm and it says its for hydroponics :(

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.

Bro can i use body scraper/scrubber means rough net that we scrub our bosy with soap😅😊😂

I'm having a problem with my project. I can get EC temperature and humidity values ​​from the serial monitor. But I wanted to send these to thinkspeak. I wrote the appropriate code for this, but it gives an error for pins other than A0. for example A1 A5 etc. After doing a little research, it says that it is because I chose the esp8266 generic card. Is that why you only sent warmth in this video?

Dear Pierre, could you please turn on the video subtitles?

My friend, how size pump can handled this set up?.thanks

Very informative and clearly explained.

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.

It's no longer available the code?

holy moly, this youtube channel is a hidden gem. thank you this helped my research a lot!

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?

It's just amazing but what we should change to run it in esp32

With this project you be able to turn pump for seconds and of for an hour, thanks

learning from Argentina, we hope to put it into practice soon, very useful to help many, we hope

genial
