th-cam.com/video/xnPIsrxVozM/w-d-xo.html
amazing. best video on.ph.sensor. thanks.for.sharing
Thanks for the tutorial. It works....
congrats, you get new subscriber
Thank you, nice video, nice music..
For calibration you will need pH 4 and ph 7 buffer solution. Use a sketch to read the voltage on the analog pin and write down the voltage with each buffer solution. Then plot the values in a graph, you can find tools online to help you do this very easily. Then add the formula y = mx + b to your code, the values of m and b are easily found in the graph you just made. Where you have float phValue, change that for: float pHVol=(float)avgValue*5.0/1024/6 and under that: float phValue = m * pHVol (x) + b;
This will give you far more accurate readings

Great video! Thank you!!
How interesting!
cool! thanks!
Nice Insight! really great! btw is it possible to use this for industrial application?
I just bought one of those sensors recently and now I have this fantastic tutorial to follow, thank you for the information!
if you face any problem let me know in a comment. I am always here to help you.
thanks for your video. quick question: can you leave the probe submerged in a body for continuous pH sensing? Or does it only work for samples of the solution. I ask because I would like a continuous pH reading for my hydroponic solution.
This is a laboratorial probe. You need an industrial one. Also available at DF Robot.
can you give us name of industrial sensor module???
Hey, i have a question. I have pH probe E-201-C. Will it work on that type of pH probe ? Its for my school project, will appreciate it if you can answer it. Thanks 🙏
Thanx for the awesome tutorial. before I buy the kits, I have a question. Will it work if the put the meter directly into the glass, with the lid open? Or into a tank?
I want to know too. Because if we have to pour the liquid into the tiny cap and screw it in manually every time, it is pretty useless. We might as well use a cheaper handheld ph meter tgat shows the reading on an lcd screen. The whole point of arduino is automated measurement. All that manusl screwing and unscrewing defeats the purpose.
@@danielch6662 Yes, it can go directly into the tank
Dear Friend 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.
Excellent tutorial .. Can you add a peristaltic pump to control the PH level? Then after that you share the code?
You can. You'll have to write the code.
hi i'm trying this experiment myself and when I try to upload the code to my arduino I get an error stating "'SensorPin' was not declared in this scope" , is there a way to resolve this isue ? great vid btw keep it up !
I used the same program but the different ph sensor (same appearance but no variable resistor and the brand is DFRobot) how do i suppose to calibrate that? pH 4 buffer solution displays pH 7.10 there on serial monitor and pH 7 buffer solution displays 5.35 ph there.
HI! Is this sensor able to be completly submerged for a long time?
maybe it'd be better if you add calibration session
Excuse me, Sir. I want to apply the ph sensor with a ph buffer powder, so when I put the ph sensor into the liquid buffer pH value 4 in the serial monitor displays a pH value of 5, then I rotate the trimport to set the serial monitor to be a pH value of 4, is that the correct way in calibration process ,. Thank you in advance if you please answer.
Thanks for the tutorial, please can i insert this sensor into water for monitoring the pond. fish pond?
yes, you can. I also dipped this sensor in liquid.
Did you carry out the experiment? Could you elaborate on how you managed to insert it in the pond and get the results?
Hi, great tutorial. Do you know if its possible to make an array of several Ph sensors with a single arduino? may I need another type of board with more pins?
How may ph sensors u want to use ??
You can use arduino mega if u plqn to use more than 6 ph sensors
Do you think this would work with aquarium water?
hi, my sensor reads 8.82ph when it 8 at 2.5 mv and 10.8ph when it 3.3 ph (soft drink -cola) at 3.09mv.
i have tried to calibrate but with no success.
can you help?
tnks.
motti
Excuse me. i wanna asking you. How to manage the voltage from power supply to be stable. because, i got the problem when pH sensor detected and showed dinamic value.
Can i use it forever inside water? I want to get a chart with changes in ph along the time
Hi, is the sensor able to be used for checking EC/ppm? Since it is measuring in milivolts it should just be a conversion. I don’t know if the sensor would accurately measure EC since it is a pH sensor you know? Do I need a separate EC sensor?
It is not.
hi, sir, I have a school project would it be okay if I used this video?
Great video thanks. Do you know if it is possible to keep the reader submerged full time without the need to screw on the end?
Same question form me too..did you get the answer?
@@kukilkashyapborgohain4643 yeah. Turn off and store in a neutral (7) solution while at rest/off.
😭🙏😂
@@kukilkashyapborgohain4643 I'm building a unit which does this. Essentially swapping out the water to test and then flushing and refilling with neutral solution and powering off the sensor. All automated of course. Best way to do it. You can also look at far more expensive solutions such too, as they are designed to last longer, but will still degrade over time if the fluid being measured is not neutral.
I too was planning on something like that. I still haven't bought the kit though. My goal is to measure PH of a big pond continuously without any need of collecting and screwing the cap. Have you tried to measure the PH by directly dipping the prongs?
does this item ship to singapore?
is the ph module calibrated?
Dear sir kindly prepare project for IOT based attendance monitoring system.....
I have already designed it. check playlist. but the full code and circuit diagrams are only available to my Patrons, you can visit my Patreon page.
if i chuck it into da water, will i be electrocuted?
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?
Danke für das tolle Projekt!
Leider erhalte ich falsche Auswertungen beim messen.
Bei der 6,8pH Lösung erhalte ich 6,39 und bei der 4,0pH Lösung erhalte ich 5,2.
Was ich leider nicht ganz verstehe, wie das mit der Kalibrierung funktioniert?
Wie sieht der ganze Skript mit der Kalibrierformel aus?
Bitte euch um Hilfe.
Danke
Hello! Can you please help me out with a 15 seconds video on pH sensor measuring the pH of milk?
Hey man please answer... What's the best way about doing this but over WIFI? My setup is in the room over if you can just give a board alternative to the UNO that would be great.
i have another video on wifi. check playlist.
is this ph sensor can use for soil ?
to measure ph for soil
could you kindly tell what is the 3.5 in (phValue=3.5*phValue; )
Can you made a video how to do ph meter for aquarium using Arduino
Sir I am going to build up a project using some sensors, so is it possible for you to give me the codes for arduino?
can we make liquid alcoholmeter sensor
sir my sensor is giving ph as 17.38 for clean water
can u please suggest the solution
can i use this sensor for underwater (2m) measurments?
Ya of course you can. Give it a try.
sir i have a question can this sensor measures the solution acidity or basicity rather than water ?? i want to take this sensor as biosensor ? can it be done
i think.you should watch my video on tds sensor. that will be a good choice.
Can ph of saliva be tested using this sensor ?
Sir may i ask, how to transfer the data from the laptop to the phone's user? Can i just use the esp32 module via bluetooth?
you can use.
does this works with ground or is just for liquid?
Liquid
I have this hooked up to the arduino as described on the electronic clinic site (www.electroniclinic.com/ph-sensor-arduino-how-do-ph-sensors-work-application-of-ph-meter-ph-sensor-calibration/), and the code is providing a difference in response if contact is made with the PH4502-C piece, but not showing any difference when the ph sensor is attached and I change the solution. Is this indicative of a faulty sensor? Again, the chip seems to function as expected, but the sensor attached provides no difference when in water or in a reference solution (ph 4.01 and ph 7.0 were both used). Thank you for your help!
No explanation of the pH formula?
Can I know whats software that you use for make the coding? I need to know cause it's urgent. Please help me. Answer me
its the Arduino IDE
is that work for soil ph?
ya, you can but will need some modifications which I will explain in some future videos.
the sensor came with a liquid on the tip what is that? I never opened it
It's possible change the Arduino for a SP32 for the práctice?
I have used it with esp32. Check my playlist on iot projects.
it does not work , cant run the code, what shall i do?
Pls help me I want complete working of iot - water quality monitoring ardino .ph ,temperature,turbidity,flow,I searched this seminar topic many sites .but ididnot get the proper result.Pls help me I'm mca student,I want full working.about one week I'm searching for this seminar topic,my topic just approved,I want complete complete working of each sensors ,ardino,etc.......otherwise my seminar topic will be rejected on tomorrow.
Can this work by using a Node MCU ESP8266?
Yes. I have a video in which i used the ph sensor with nodemcu. Check playlist
how does it takes before the pH sensor generate a result?
for more details visit my website. you can find a link in the description.
The link for library is not accessible
the server was down. now it available. Sorry for the inconvenience.
This sensor canbe calculate oxygen in water and temperature .
watch the video it's already explained in the video.
Can it work with running water?if not is there any way
Ya you can use this.
is it work to send result via WiFi ?
yes. i have a video on this. check playlist.
Can it to be online monitoring? 🙏
yes. i have the iot version as well. check playlist.
I cant find the link to the code displayed in the video
It's available on electroniclinic. Com
Can you tell me approximately how much you used to buy all these components
i am working on another version, in which cheap pH sensor is used. i think you should wait for 6 days.
@@ElectroniClinic pls tell as early as possible.Thank you
I can not download the code.
Its available on my website. Check link in the description
Hi, Can I use it for Raspberry Pi?
yes
how do i do it?
Oh that music 🙄
will it workwith bluetooh?
Yes
@@ElectroniClinic does the code different if so where can i search for it
watch my video on iot water quality. in that video, you will learn the serial communication. just replace the nodemcu module with the Bluetooth module, that's it. you can download the cell phone app from my website.
Bro I want pH sensor interfacing with raspberry pi please help me
hi can i get the code for raspberry pi 3?
can use with esp32?
yes
soon i will add a video on the hydroponic system
@@ElectroniClinic wow that great
Can you add the code in the description
It's available on electroniclinic.com
sir my sensor is giving ph as 17.38 for clean water
this is my code
float SensorPin=A0; // the pH meter Analog output is connected with the Arduino’s Analog
unsigned long int avgValue; //Store the average value of the sensor feedback
float b;
int buf[10],temp;
void setup()
