Hello, how do I measure the Electrical Conductivity of water samples with NodeMCU, Display the result on a webpage in real-time and then store the values in a DataBase. What sensor do I use and how do I go about it.
Dear Sir I have a question . as I see that this TDS measurement device range is between 0 to 1000 ppm so as I see from your video and link TDS reading is 1840 PPm so is there any limitation or 2500 ppm is also possible to read with this TDS measurement device. I thank you for your reply.
Help me friends, i'm having a trouble with the sensor i bought. I read 20 ppm with the TDS meter i have and the new sensor is reading 2944 ppm. The liquid that is 240 ppm the sensor is reading 3109 ppm :( Is this a fault of my sensor ir that is something else i can do?
Updating! I found out the problem after I bought another TDS meter... it was my ethernet shield. After i took it off, the right measure could be read by.
I read the spec of this gravity tds sensor reading range only 0-1000ppm, i see in your video the sensor can read up to 1900ppm, i will test this sensor for hydroponics, i need to read up to 1100- 1300ppm.. what do you think, can i use this to read the nutrient water? just for 5-6 second read the water tds value than off.. and decide whether the nutrient pump adjustment on or off... so the sensor only has a voltage for a short of time.. is it possible if we give the sensor a voltage for longer time to read out of senor reading range will break the sensor module?
From the specs the sensor can measure only upto 1000pm. But the sensor shows the result upto 2000ppm. Need to verify this whether the data is correct or not
im using esp32 to show the result in serial monitor but the result in not showing what kind of changes i have to made in your programming plz guide sir
Hi friends I need help. The display do not shows numbers or letters. I checked the connections several times, there is no mistakes. I have charged the sketch several times, but the system does not work
@@HowtoElectronics Hello. Yes I did full clockwise and counterclockwise, just appear 16 squeres, but no letters, numbers or signs ! It is curious, but do not works for the two sketches, with and without temp sensor projects Thank for your help
I have not used temperature sensor and used Techtonics analog gravity tds sensor available on amazon. While connecting it was showing ?? Like characters. After changing the baud rate of serial monitor it started showing 0 ppm. After insertion of electrode in water also it shows 0 ppm. And for lcd displays nothing. Display light is turning on and off quickly. Changed the delay to 5000 and it started turning on and off quickly in every 5 sec.
what is the use of the 4.7k ohms resistor? i tried it without the resistor and the value of the TDS and temperature outputs negative but when i include the resistor it works can someone explain the use of the 4.7k ohms
It is used for parasitic power for DS18B20 sensor. The digital pin requires power which is supplied via 4.7k resistor. If you dnt use resistor, the temperature will be shown as -127.
hi, help me please. i success to calibrate the tds sensor, but i need to have the sensor work properly even the power supply can sometimes be turned off. cause the tds sensor need to be calibrated first to work properly if after the power supply is off. can u help me please? :')
I want a small display for my water filter to know the tds and ph in digital format all the time to know these parameters as my water source changes sometimes municipal water comes or borewell water or tanker water comes so I want a online display of the parameters. Can anyone suggest a solution
Heey, i uploaded the same code, but it doesn't work, it shows me in the serial monitor : "?????????" , I don't know where is the problem.. i have conductivity sensor with EC board V1.0 , thanks for answering me
Changing to baud rate in Serial monitor gives 0 ppm for every reading also my lcd is flickering for this code. For simple display code display works fine for same connection. There was problem in the sensor. I replaced the sensor and changed the baud rate in serial monitor. Now getting the desired output.
Hi, i got gravity tds meter from DSRobot. It has sensor range from 0 to 1200 ppm, but my sensor sometime can reach to 1800 ppm (9 times in 147 running), can you suggest what should i do? this is for my univ project :) thankyouu
The sensor range that the manufacturer writes is mostly not accurate. When they say 0- 1200 range they mean it's reliable in that range. Check your solutions tds using another market bought meter and calibrate it in your code.
Hi I was planning to do that a month ago. But becoz of lockdown I don't have necessary hardware with me right now. I will do that in couple of month soon.
@@HowtoElectronics actually I want to combine this one with your water speed and amount filling program So basically I want that this to measure the tds of water running from that pipe attached with water flow sensor to measure amount and speed as well

What sensor do I use and how do I go about it.
Another amazing video, keep posting such videos 🥰🤗
Thnq u brother for this amazing video I am just looking for a video like this...Nd now I just found it thnq u so much...Nd keep it up
Salam brother.
Please subscribe my channel and support me 😍
Walaikumassalam...done brother 😄
If whole tools hold in a box except the sensor, can it considered explosion prove?
question: why does the serial bit rate set to 115200, not the usual 9600?
Baud rate is an option. Choose what you want!!
can you tell how to complile all your codes like for temperature ,lcd,tds..which was given in discription ?
Use Arduino IDE. You can learn from hundred of tutorials about Arduino and you can make it without problems.
Thank you, but I do have a question.. can I connect this sensor to PLC?

The maximum ppm could be 2520 and value varies according to different ionized solute.
@@HowtoElectronics thank you
Thank you sir, your video is very helpful for me..
Helpful information video

Updating!
I found out the problem after I bought another TDS meter... it was my ethernet shield. After i took it off, the right measure could be read by.
How about an LCD with an IIC connected to it? You think you can make a video about that?
Your tutorials are very helpful. Thank you so much. Can you please provide proteus library for TDS meter? Or how can I find it?
Do you have any reference for using two conductivity cells? I need to calculate a direction between two cells.
Did you solve your problem?
I read the spec of this gravity tds sensor reading range only 0-1000ppm, i see in your video the sensor can read up to 1900ppm, i will test this sensor for hydroponics, i need to read up to 1100- 1300ppm.. what do you think, can i use this to read the nutrient water? just for 5-6 second read the water tds value than off.. and decide whether the nutrient pump adjustment on or off... so the sensor only has a voltage for a short of time.. is it possible if we give the sensor a voltage for longer time to read out of senor reading range will break the sensor module?
From the specs the sensor can measure only upto 1000pm. But the sensor shows the result upto 2000ppm. Need to verify this whether the data is correct or not
Bro can you please let me know
Instead of gravity tds meter we can use keyestudio tds meter
Yes same board.
im using esp32 to show the result in serial monitor but the result in not showing what kind of changes i have to made in your programming plz guide sir
Can you share online simulation link please
can I calculate ppm in the range of 1200 - 1800 using this tds sensor?? if not, what sensor should I use to calculate the ppm with that range
thanks for this video.
can this be used on esp32?
Yes. ESP32 is better, just change VREF to 3.3 and resolution to 4096.
Do you have TDS Sensor library for Proteus?
u got?
I cant change the A1 to any pin number? Why is that?
Thank you for this.
Loves the video quality of this video.

Hi friends
I need help. The display do not shows numbers or letters. I checked the connections several times, there is no mistakes. I have charged the sketch several times, but the system does not work
Did you rotate the potentiometer to adjust the LCD contrast.

@@HowtoElectronics Another thing noted is, the light of the display throbs
Same issue with me For serial monitor I am getting 0 ppm continuously and for lcd display it is throbbing.

Additional water level indication possible aa?
hi, what is the max ppm reading
Hi How much do you charge for Adrino consultancy?, I need to make a new type of colloidal silver generator

how if the ppm more than 1000...can this sensor read the ppm?
What kind of TDS are you using

You dont need to calibrate again and again. Initial calibration is enough. The sensor works well even after switching the circuit on/off.
Hi, this sensor work with milk??
What the application that you use to make tha schematic design sir?
Fritzing
Do you have chlorine water sensor??
Hello, if i wnat to connect with firebase ? How i do it ?
if i use 3.3V then at the place of 5V in the code i will have to write 3.3 V right?
TDS Sensor doesn't work at 3.3V I suspect.

Look at the bautrate
Same issue

There was problem in the sensor. I replaced the sensor and changed the baud rate in serial monitor. Now getting the desired output.
I corrected lcd flickering by providing 5v from arduino to positive leg of the potentiometer.

Sir, What happens if sensor pin are short
Where can i find code for ardiuno
thanks for the video, how do you calibrate the tds sensor ? or does it need calibration or not ?
It does not need any calibration if you are using temperature sensor.
@@HowtoElectronics can it measure ppm above 1000ppm? if it can, how ?
Ho copiato e incollato lo sketch,ma continua a dirmi il valore A1 non è stato dichiarato...... aiuto please
select the board... tools - board : arduino uno
For what use is the potentiometer?
To change lcd contrast.
hello brother, do you mind if can make another code that will support nodemcu and thingspeak instead of lcd and arduino uno -thanks

Where is the link to buy TDS meter?
Sir ,I want this full kit ,how i can buy this
This is very nice. Can you please send me the link for the code and lib files.
Could you give me TDS Sensor Library for Proteus
What is total cost this?
can someone help me download the library?
TDS sensor is conductivity sensor?
Yea there is a mathematical formula to convert tds value to ec
@@HowtoElectronics formula?
Check one of my post on my website article. I have designed the IoT based TDS & EC meter. You can find the formula there
