    To calibrate properly you need ph calibration fluids, usually 4.01 and 7.01. Then add this to code:
    Before setup:
    float calibph7 = 2.50; // example voltage at pH 7 calibration point
    float calibph4 = 3.00; // example voltage at pH 4 calibration point
    float m;
    float b;
    In setup:
    m = (4.0 - 7.0) / (calibph4 - calibph7);
    b = 7.0 - m * calibph7;
    In loop:
    float Voltage = analogRead(Pin) * 5 / 1024;
    float phValue = m * Voltage + b;
    This will give you very precive measurements even with cheap sensor. You can use something like ads1115 to improve accuracy.
    Also i recommend setting the pot to 2.5 when probe is in pH 7 calibration fluid.

    i just wanna say you guys are one of the best... if not, the best when explaining these stuff to beginners!
    i hate watching TH-cam videos for "beginners", and yet the person explains it like they're talking to some experienced engineer.. though i could understand what they say, i just hate it cause they're not "teaching"... they're only "showing".. and sometimes they come off as arrogant to me, cause its like they expect everyone to understand what they're showing..
    though the electronic clinic shows their expertise by knowing how to make someone with no idea in the electronics field be knowledgeable in just a couple of videos..
    simple demonstration, simple and easy to understand code.... English is not your primary language, but i appreciate how on every video you do your best explaining things so that you could help as many as you can.. you deserve more views..

    don't underestimate the importance of cleaning your pH probe with the cleaning liquid. Before cleaning I got a reading of 0.5V in water and after it I got 2.8V. Still some calibration to do, but the difference is VERY big.

    • @JuanjuGomez
      @JuanjuGomez 20 วันที่ผ่านมา

      It's a mathematical formula, you get the value of pH like this:
      y=mx+b
      the equation of the line, you get that by measuring the voltage of the Po pin from the sensor. you need to do at least 2 measurements then you have this:
      phValue=m*voltage+calibration_value
      phValue is know from the standard liquid, like 7.01 pH, then you measure the voltage, yo get something like 3.86 volts.
      clean the prove and then measure another standard liquid, like 9.18 pH and you can get something like 4.20 volts,
      got 2 equations,
      7.01=m*3.86+b
      9.18=m*4.20+b
      find m and b, that's it. b is calibration_value=21.34 in his case. you can get a better approach doing that on excel, charge the y and x points there and it'll give you the equation of the line. pHValue=m*voltage+calibration_value.

  • @_general_error
    @_general_error ปีที่แล้ว +1

    oh man... that's not how you use a pH sensor! You are not supposed to put your test samples into the cap, that's only for holding pH sensor solution (KCL solution). You are supposed to keep the sensor submerged in KCL solution when not in use, and no other liquids are allowed in the cap of your ph sensor, you are decreasing life of the sensor drastically. Instead you are always supposed to put the probe into a beaker holding your sample and there needs to be a gentle movement of the liquid around the probe.

      That because the analog pin on esp32 can only be activated with 3.3v input.And if you using sensor with 5v work voltage like this pH sensor it wont show you the same amount of Analog Signal as you using another board like arduino which is it can be activated by 5v on analog pin.
      The maximum analog signal output you can get if you use esp32 is 2800 at 3.3v max.

      this is a common problem, i have a 400$ ph/ec meter, if i try to use both probes in the same container the reading is unstable... it has something to do with them sharing the ground.
      i also cannot read either ph or ec directly from the tank, other equipment like heater or pumps may interfere, somehow there is some current messing with the reading, try turning off everything else in the tank while reading ph to see what is causing it.
      somehow you must isolate the currents

      You have to get these values by measuring the voltages of at least two calibration solutions, usually PH 4.01 and PH 6.86. The sensor is linear so with these voltages you can solve y = a x + b for a and b, with a the slope (which is always negative, higher voltage = lower PH/more acidic) and b your offset/calibration value.

    Hello, I have a problem. Help please.
    I am using the Nodemcu ESP8266 board and microship which are quite similar to Arduino. I have been testing with a potenciometer if the AnalogRead() is working well or not, and yes it is. But when I connect my pH sensor, the programe reads always the maximum voltage(1023, if I map it 5.5...etc)and there's no way ro regulate it using the screws, it won't go down.
    What do you think? Is it worth it to buy new pH sensor? could it be something else? I have followed all your steps and watched first 8 minutes many times.
    Thanks! Have my upvote anyway if i get the solution or not!

      Instead of powering it up with 5V, use 3.3V from 8266 board. It will work.

    good morning friend
    I bought this sensor, however when I calibrate it in a solution with ph = 7 as you did, and put it to read a ph = 2.5, it is reading a ph of 5, what did I do wrong? Would you help me?
    my question is: if i want to read a solution close to 2.5 do i need to use a solution for calibration close to that?

    • @ralphbooger4756
      @ralphbooger4756 3 ปีที่แล้ว

      the ph reading is a conversion of a volt reading, 0-14 ph is converted from 0-5 volt... so at 2.5 volt it should read 7ph... either way, after uploading the code, put probe in ph7 solution, then adjust the potentiometer until it reads 7ph, if you want to check accuracy further put probe in ph4 solution and see what it reads, if it is reading 4ph or very close you are good!

    • @angelhernandezvega6064
      @angelhernandezvega6064 2 ปีที่แล้ว

      2.5 Volts is half of the total voltage (if you have it wired to the 5V output), and the scale of pH this can read is from 0 to 14. When shorting the sensor, it should read half the voltage, which would represent 7 on the pH scale (half of the max pH value)
