Ph Senor Arduino Interfacing Tutorial | Working, Calibration Method & Code

- In chemistry, pH is a scale used to specify how acidic or basic a water-based solution is. Acidic solutions have a lower pH, while basic solutions have a higher pH. Thus Ph sensor has the ability to determine the Ph of any solution, i.e it tells whether the substance is acidic, basic or neutral in nature. By knowing the Ph, we can monitor the water quality in Agricultural Farm and also in Fish Farming. Similarly, Ph Sensor has a wide range of applications like wastewater treatment, pharmaceuticals, chemicals & petrochemicals.
In this basic tutorial, we will learn how to interface Gravity Ph Sensor with Arduino. We will design a simple Ph Meter and display the Ph value on OLED/LCD Display. We will also learn about the construction & working of the Ph Sensor. Finally, we will learn the calibration method which will determine the correctness and accuracy of the sensor. The Ph Sensor can also be interfaced with other higher-level microcontrollers like NodeMCU ESP8266 & STM32 which I will discuss in the future.

omg thanks you so much, i tested differents types of codes and you was the only one that it worked
nice presentation of pH meter, will try to make the project for laboratory use, thanks
Very good and funny videos bring a great sense of entertainment!
Best and easy way to measure ph Value of diffrent liquid material...thanks sir
Can you please keep the code link
@@UdayKumarDaida-hc3gr
Link is already there in the description box
thank you , i understand better with this video
Another awesome tutorial 🤗 Hope to see more tutorials like this 🤘🏻
Thanks you helped me ❤️
Nice project
Nice video I like it
Te lo agradezco mucho bro
Thanks for the tutorial, how to clean up the electrode?
great stuff, just wondering do have a video on setting up a relay that would operate a peristaltic dosing pump and auto administer a ph up or ph down fluid for a hydroponic reservoir?
Well explained video. Very helpful 💕😍
Thank you
When I put the sensor in the pure water, it display ph around 13. So I turn around the potentiometer, but the lowest it can go is around 8 only?? What else can I do to get more accurate reading??
Is this safe in refineries, especially the sensor no possible sparking?
Can the system work continuesly for long time. I mean if it is continuously dipped in Salt solutions for long time will it work .. if yes how long it can work.?
Gracias. Thanks. Merci.
Can we connect PH and DO to same Adino...if yes...which Ardino need to use ?
what is the role of the ph sensor module (or shield) ,the little card that links the probe to the arduino card?
I do not have this module and I cannot obtain it, How could I replace it and make everything work?
In which program did you make the connections?
Good video! Thanks... where did you make the pH and Arduino Schematic?
Using fritzing software
sir which amplifier sensor module is being used here
how can I get ph sensor library for proteus and arduino uno,sir?
does that code easily run for atmega2560? and do u have its simulation on proteus?
how do you do the effect of hand writing?
Sir, for calibrating I'm using milk and when I'm trying to rotate potentiometer after some time the values are becoming constant sir those values are not changing sir, please tell me the way sir to solve this problem
Sir, your library for Liquid Crystal_I2C.h is not available...Please helppp
do you have the libraries in proteus?
Hi sir, help me to combine two sensors pH meter and Temperature in arduino
Top,thanks for sharing .
what software used to create those graphic schematic?
Good explanation
Can you please tell me if i drown the ph sensor in a water tank for a very long time then , will some problem occur in ph sensor aur not ??
The pH sensor need to be cleaned and calibrated regularly may be after 15 days.
You cannot keep it for a long time without cleaning.
@@HowtoElectronics okk
Thank you so much sir
Tem algum projeto para medidor de orp ?
Awesome vid: - great vid - awesome. How to draw a sketch diagram - here!? - i need a sketch diagram for wiring; i want to do some work with sensing ph in Coffee and water - Can you help here out!=? Look forward to hear from you
ok sir nice video but ii want to know about auto calibration with two tact switches one for 7.0pH and 2nd for 4.0pH buffer. how it possible please send me the code
where can I buy this?
sir im getting ph value and voltage is 0 what is the problem sir
Can we check ph of harsh chemicals like concentrated sulphuric acid and potassium hydroxide without damaging it, and what about its accuracy, and reliability?
It works well with these chemicals.
Awesome video.. Helped me a lot. Quick question, can I use this sensor 24/7 in my aquarium???
You can use but you have to clean the sensor once in 15 days regularly to get the correct calibrated reading.
@@HowtoElectronics Great, but the lifespan using it 24/7 do you think is good? How would be good to clean it? Fresh water?
There is a solution available in market to clean it and calibrate it. Check my website documentation, I have mentioned it there.
@@AllanRomanato No, you can't. This probe is a laboratorial one. You need industrial one.
Which basic solution add to get neutral?
i have arduino mega 2560 but i cnt upload the proggram in it do you know why sir ?
How costly this kit?
And how we buy?
Does the device need to be connected to the power source/ laptop in order to know the pH Value?
Either connect to laptop or any 5v usb or dc adapter power.
Can I use it continuously in a Bio Floc Fish Farm to automate things.
Yes you can use
how long it can be submerged for continuous long term monitoring?
15 days
Mr how you got 3.5 for pH value?
Thanks for totorio can you provide us the source codes link ?
Can i use it for measuring soil ph level.
Yes you can
Can we use this sensor for soil ph testing ??
There is separate video on soil ph sensor part. Check the channel Videos for that
How to make circuit diagram for this which software should used for circuit diagram
Fritzing
sir can i dip this in my aquarium for experimentation sir?
No sir
Which aurdunio are you using?
Uno
Sir, do you have ec sensor tutorial?
Yes check the website article. I have made an EC meter using TDS sensor.
@@HowtoElectronics it is ec sensor and tds sensor same?
Can the sensor be permanently installed in a water tank to take automated measurements continuously?
Not at all.
You have to clean in 15 days regularly and recalibrate it.
@@HowtoElectronics Thanks for your clarification. Are there other sensor types which never require any human involvement once installed?
Not at all, there are no such sensors. Even I have been looking for such sensors since long time.
@@HowtoElectronics Ah I see
Thanks again.
Is it used for checking vegetable spoil?
You might try
@@HowtoElectronics thank you
How much this ph electrode ??
Sir it work on soil I am farmer I want to measure ph of my soil
Sorry it doesn’t work on soil, its only for liquid. To measure the Soil ph there is a different sensor. I will make a video on that within 15 days. So stay tuned and wait.
Should we download library?
No library needed
We are very close to 9K
Yes bro, Thank you for the love and support. 😍
tengo un error en #include
Arduino indica que debes instalar esas librerías
my sensor always output 15.45 ph
One point calibration with milk and nothing about 2 or 3 point in code? Disappointing.
There is no discrimination here. Your accent of English is terrible. Very very hard to understand. I would like to suggest you spend some time to improve your pronunciation before you showing it in the public. Or you can speak in your mother tongue. You don't have to speak English here.
I just wondering how you people get educated about English. What do your teachers think about the result. Terrible. I like the topic but hate the way you treat English. Generation after generation, no improvement. Just like circuit, there are rules you have to follow, protocols. Please respect the protocols. I must let the Queen know what a mistake once British conquered India and did not issue a law to correct the accent.
Thank you for all your suggestions for my betterment and improvement. But we belong to subcontinent and we can speak 4-5 languages. And the accent depends upon the mother tongue. No matter you have a PHD degree in english literature, your pronunciation and accent remains the same.
This accent is fully understood by the people on India, Nepal, Bangladesh, Pakistan and all nearby asian countries.
I would suggest you to learn our accent. Anyway thank you for suggestion, will try to improve it.
