Project Description:
********************
This is the analog pH sensor kit from the DIY MORE which is a bit different from the one developed by the DFrobot which I have already used in some of my previous videos explaining what is a pH sensor, it’s working, Calibration, and how to use a pH sensor to find the pH value of different liquids. I also used the DFrobot pH sensor kit for measuring the water quality using the Arduino board and I also used the pH sensor kit from the DFrobot in an IoT based water quality monitoring system using the NodeMCU ESP8266 WiFi module. So, if you want to learn how to use the pH sensor kit from the DFrobot then I highly recommend watching my previous videos.

i just wanna say you guys are one of the best... if not, the best when explaining these stuff to beginners! i hate watching UKposts 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..

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.

Its working good only issue is the variation in value from 2.0 to 9.0 when i put probe direct in aquarium but read stable value when i put water in separate small bowl, plz guide me what can be issue of pH value variation, is voltage set at 3.5 instead of 2.5 is issue.

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.

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 2 роки тому
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!

may i ask. why calibration value is 21,34?
@TheExstud
@TheExstud 3 роки тому
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.

hii bro,for me the pH value is showing as 14.08 and some very small variation like 14.05,14.09 like this.... can you pls help me bro

My pH Sensor can only calibrated down to 3.97 Volt? Is there some problem with the probe? Please help! Thanks!

After adjusting to 3.3 volt due to WeMos Mini, the analogRead only go down to 830 (max 1024) with 2.68 V? Any reasons? Thanks!

Hi friend, did you got some advice about your situation? I have the same issue, I can't down below 2.7 😓 I'm planning to adjust by code, x= voltage-0.02, but I'm no sure if this don't affect to ph measures

When trying to adjust the output with the trimmers the value does not move at all. Does anyone know the solution or is it a faulty board. My value only displays 4.26V.

why do you need to setup it to 2.5 volts?
@angelhernandezvega6064
@angelhernandezvega6064 Рік тому
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)
