DIY IoT Water pH Meter using pH Sensor & ESP32

[@legendfpv]

Lemon juice is pH 2.0... not 3. Also you never showed the calibration.

[@soumyachaudhary9839]

From where did you make this circuit diagram I mean which app

[@lifeisgood6076]

Why my ph sensor keep showing 14 ph or 4095? Pls help this is my fyp.

[@legendfpv]

pH = vRef * voltage? That's the formula for pH?

[@Smarden]

That was a really cool project. You explained it really well.

I'm working on a water quality monitoring project using ESP32 WROOM, pH4502C, and EC Board v1.1. I'm facing challenges with connection and coding the components, especially during the pH offsetting, which isn't producing the expected results. I'd really appreciate your help in resolving these issues. Your expertise could make a big difference in achieving the project's goals. Looking forward to your guidance! Thanks!

Hi, Can we put if then else to catch particular PH value? My use case is that if pH is greater than 67then switch on a co2 solenoid in my planted aquarium, Solenoid regulators are 240 volt operated ones which if switched on allows co2 gass from the cylinder to flow out controlled way and a diffuser in the aquarium diffuses the co2 in the water , thus slowly increasing the acidity of the water which should lower the ph ,. once ph value is less than 65 then switch off the solenoid connecting plug. So a relay is required I guess and a piece of code that does the switiching within the if condition. --- Please let me your thoughts on this. Also if you can make such a device say I buy 10 of those how much would you charge me. I am from Kolkata. Let me know if you are interested. Thanks

My ph module it show correct ph in buffer 250ml. But when i put to water tank 200 liter values unstable 5-9ph whyyy

[@Hazar-bt6nf]

Can it be done by raspberry pi? Everythibg is same just instead of ardu use raspb??

[@electronic7979]

Super 👏

[@kiranmahapatra8716]

👍 very good explanation.. if pH value not match with real value, how to do the calibration.... Can this type of pH sensor be use in real field (outside) or only for lab/experiment..

[@HowtoElectronics]

Yes you can use it in real life applications. But you need to recalibrate the device after each 1-2 months.

@@HowtoElectronics thank you

[@nandhinijagadeesan3835]

How to connect with Arduino mega and 9v battery? Circuit connection??

[@GrayLogix]

Very nice video

[@tenadepee1603]

what does it mean "const int potPin=A0", ?

[@Jptoutant]

is it possible to leave the electrode submerged permanently?

[@lazytehcno12]

can use power the pH Sensor use VIN from esp32?

[@vinay6686]

The code has some errors and not showing the ph value when we used the code for esp8266

[@stevenpwilliams]

Nice job, but thinking you ought to flush the probe after storage and between solutions.

[@afiffarhati4580]

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?

[@lukaduffaut6875]

not sure but there is an equation to get the Ph with your potential difference measurement et the temperature, you'll have to use it

[@CurrentElectrical]

Video starts @2:07 if yo don't want to waste time on ads ;)

[@rehan_alammmblogs]

Nice 👍

[@FukaKiryuin-z3h]

Do you have a same video But with esp8266 ?

[@shankarps8561]

How much price u spent for this project?

[@HarshGoel]

Very well explained. I hardly know electronics but could understand this. Can this work with Android mobile also, instead of laptop?

[@ashwijkumar7583]

This is an amazing project, and I am trying to implement it. But after doing the connections i am getting pH values as 0.13. What should i do?

[@bonbonpony]

Now I challenge you to make a DIY pH sensor :q Just buying stuff and combining it together is not DIY.

[@AirEater]

of course the person that's a brony will complain.

[@AirEater]

Cringe ngl

[@bonbonpony]

@@AirEater I'm not a brony, that's one. And even if I was, that would have nothing to do with my complaining, because YOU brought the subject of ponies into this, not ME. I was talking about pH sensors. And if you're looking for cringe, you don't have to look any further than your own comments.

[@AirEater]

@@bonbonpony ok to be fair you do make a solid point. i accept the fact i'm cringe

[@HarshGoel]

Very nicely explained. Can you please tell me if I can do this with an Android mobile also, instead of laptop?

[@HowtoElectronics]

Yes it will

[@adishapte4167]

Can it work with Raspberry pi

[@momacrt6168]

Hey i love your work can i send you a. Message ? Do you have an email ?

[@agustineliam446]

What is the name of online simulator you had use to design a circuit?

[@rizwan6579]

May I know the name of simulator used?

[@lazytehcno12]

doesn't work

[@SonuSingh-qj5xz]

Any anyone tell me what material is required

[@HowtoElectronics]

Its already given in website link.

[@haydersaidi]

thank you

[@muhilas7750]

What type of jumper wires are used?

[@HowtoElectronics]

Any conductive wire will work

[@martinkaspar5095]

awesome project i love it

[@mramzadg]

Good project 👌👌👌

[@infinitegaming2897]

Awesome project

[@Lisalisa-kx9fw]

Awesome video 😊 I've learned much. 😄😄😄😄

[@MikhailChurikov]

Thanks for the great explanation how the sensor works
