Project Description:
********************
Declining water quality has become a global issue of concern as human populations grow, industrial and agricultural activities expand, and climate change threatens to cause major alterations to the Hydrological cycle. Every year, more people die from unsafe water than from all forms of violence, including war. Have you ever tried to find out what is the pH value and TDS value of the water you are drinking? Using a pH sensor and a TDS Sensor you can make a perfect water quality monitoring system. I have already used the pH sensor with Arduino and Nodemcu esp8266 wifi Module for measuring the water quality you can find links in the description.
In today’s episode, you will learn how to make a water quality monitoring system using the Gravity TDS Meter V1.0, DS18B20 Waterproof one-wire digital temperature sensor and 16x2 LCD with Arduino for measuring the TDS value. TDS stands for Total Dissolved Solids. The TDS value as you can see on the LCD screen indicates how many milligrams of soluble solids are dissolved in one liter of water. Many TDS meters display the TDS value in ppm which stands for parts per million. In general, the higher the TDS value, the more soluble solids are dissolved in water, and the less clean the water is. Right now the water under test is excellent as the TDS value is less than 300. The TDS value starts increasing as I start adding the salt. So, using this small DIY low-cost TDS meter you can find out if the water you are drinking is clean or not.
Along with the TDS value, you can also see the EC and temperature values which I will explain in a minute. I will also explain what TDS value is good for drinking water? I will explain all the three parameters in detail.
You can also use a TDS pen which is quite cheap and can be used for measuring the TDS value. But, if you are planning to make a hydroponic system that maintains a certain ph level then the TDS pen will never work. Because for hydroponic systems you will need an automatic system that can turn on and turn off other electrical devices. Moreover, you cannot use this TDS pen in IOT based projects.
But this TDS meter can be used in automatic Hydroponic and IOT based water quality monitoring systems.
Without any further delay let’s get started!!!

Great video you have a good voice for teaching, but like others mentioned, the device says it only measures up to 1000ppm, how is it displaying higher than this and a 2.3 EC this is way higher than 1000ppm. You even mention the max output is 1000ppm, so if the full voltage at 5v is 1000ppm how is it reading higher on the video. Thank you
Ótimo projeto e muito bem explicado. Abraço!
superb explanation ... great job !! Thanks :)
Thank you sir, but i wanna ask you about how sensor tds can read >1000ppm meanwhile maximum range is 1000 ppm ? thank you sir hope you reply my question
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
Awesome project
let me ask what is the formula for converting TDS to EC? Thank you very much
Nice project 👍
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
Thank you for this.
Super project 👍👍👍
Can we use tds and ec sensor both?
any sugestion for ppm above 1000 ?
the effect of sugar on tds value is depedant on the concentration of water percent of solution so major increase in sugar may have small effects on tds value but i guess this must not be a problem for a hydroponic system.
I'm not speaking English but no problem because i still understand whats your mind, this video very helpful for me, I want make a simple gardening with this tools, thank you so much :)
ya sure i will help you. you can add.me on whatsapp.
@@ElectroniClinic Ok thanks, what your whatsapp 😁
Nice one
how u get reading more 1000ppm , what i see data sheet on tds sensor is 0 - 1000 ppm only
Superb
how to decide kc value? Please explain
Great video.
The product spec mention that measurement range is up to 1000ppm. But, in your video, it shows >1100ppm. Can I can how is it possible?
Thanks
yess i need answer to this too :(
How this TDS sensor measure EC
Could you give me TDS Sensor Library for Proteus
I want to ask sir , what software did you use to make the schematic circuit?
cadsoft eagle
Can show EC value in 1xxx?
Correct me If I'm wrong :
The TDS Sensor you're using has a maximum reading range up to 1000 ppm, right? I just wanted to know how come it could have a reading up to 1195 ppm at 1:48 ?
Hope this question is not offending :/
amazon TDS links not working, so careful..
Good question, mine has just arrived, i'll do some testing and post back results, perhaps his conversion factor for the voltage was off.
@@GaryMcKinnonUFO any update on this please? Looking at getting one myself, but not much use if only goes up to 1000ppm.
@@CraigTalon Yes, i calibrated a cheap TDS pen with proper solution then configured the probe. I'm not measuring anything above 1000PPM (2 EC) so can't yet comment but when i set it up again (i had problems with the pH sensor and this in the tank at the same time due to EMI) i'll do a heavy saltwater test and see how far it can be pushed. I bought it cheap from ebay : www.ebay.co.uk/itm/Analog-TDS-Sensor-Water-Conductivity-Sensor-Tester-Liquid-Detection-Arduino-BSG/124356193622?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
@@GaryMcKinnonUFO
How did it go? Did the sensor work properly?
Good day
Is it possible to add more sensors to provide more data on the water quality ? I suppose whatr Im asking is can the system be expanded on ?
Ya, of course you can add more sensors.
Thank you. I tried sending a message on your site but there seems to be a problem with the email form. Please can you send me your email address ?
how can i replace the pcb board because i dont have access to order pcb board
circuit diagram is available on my website. you can solder all the electronics on a breadboard
@@ElectroniClinic ok understood. Sorry for the novice question. Thank you very much for your reply
How can I send both sensors data to firebase plz guide
check playlist, i have videos on Firebase.
Why your aref = 4,3 volts ? shouldn't it be 5 volts?
The 5 volts is just theoretical, in fact he measured from the device that only consumed 4.3 volts
Sir please provide the code link here

a great video, really helpful good work. drop me a meassage later, you have dissapeared from fb,
fb account is under review
Lol what did you do?
