Hello, I want to do an Arduino project, I need to test water for PPM and Ph. (What's inside my water). I want to detect the levels of: ph Nitrogen Phosphorus Potassium Sulfur Magnesium Calcium Iron Boron Manganese Zinc Molybdenum Copper I will purchase the hardware (sensor) you will recommend me to buy. The you will have to write/edit/install the software on an Arduino card that will report the levels of the PPM in the water. With your bid, include what hardware (sensor) you recommend me to buy.

Hello, I would like to share with video of my project in which I have calculated the ppm and pH of Water and display that on LCD and report record in SD card. I know you mentioned about the sensors details also. I will provide you with the sensors details so you can buy them. I have shipped my previous that project in which I have calculated the ph, ppm and flow of water to my American Client. If you want I can be shipped prototype to you at your destination but you have to arrange the shipping. Thanks, Chanchal K.

Hi, can you please detail if you need to measure each single element: Nitrogen, Phosphorus, Potassium... an Ph or you need to measure what is usually called "TDS" ? I kept my bid as lower as possible because I'm interested in the project as well but I have never started it, this could be indeed a good chance since I'll use the money to buy sensors, that for TDS alone ranges from 20 to 2000 $ ... Basically my goal is to get the sensors for free, if I reach this target then I'll give you the code. I think that a display with PH & TDS plus temperature (that you did not request but I can add easily) could fit your needs. If you like to discuss the proposal drop me a line. Cheers, Alex.

Hello! I know about this type of work with arduino. The same project was my project for science exhibition to be held in 2017 at Los Angeles, USA. I presented this project in Pakistan as well as in USA, I was gold medalist and finalist in my category due to the project which is very similar to your one. I have all the material at my home and can help you build your project as well in very less time. I have extensive knowledge related to your project. You can also see my certificate in my profile. for ph measurement you can use SEN0161 Arduino PH sensor. for measurements of elements in ppm you require electrochemical sensor on which we should discuss in chat. Its actually complicated. I hope to work with you! Thanks!
