How to Make an IoT based Water Quality Monitoring System using Arduino and NodeMCU

In this project we are going to measure and monitor various water quality parameters such as pH value, soil moisture and temperature. We are using Arduino uno, NodeMCU, Gravity Analog pH sensor, DS18B20 temperature sensor, and Soil moisture sensor as main components for this project.

so i made this project, just keep few things in mind.Install arduino json 5 and not 6.Other than this, while connecting to the server, renenber to keep the phone from which u are taking wifi (like ssid=admin here) has data on and the device in which u r displaying data should connected to this wifi & have its data off. also, keep in mimd to chnge the calibartion value if u get -6 like here in water for ph.THE PH SENSOR IS THE MOST EXPENSIVE, COSTED US 1600 RS and overall cost was 2500.

The PH sensor is not correctly calibrated .Its giving negative value. kindly have a look in to it again. But keep going like this. best of luck!!!

If you don't mind will you provide the connection clearly pls

[ashwijkumar]

Instead of water, I can use this to test moisture and pH of soil too right?

sir, can i know. what kind of capacitor or transistor u use?

[hihohihoi]

I need a similar tool, just with wireless sensors…any idea which to use ?

[m.wahyualfaris]

assalamu'alaikum can I ask for the coding script and examples of the mass circuit🙏

[chad]

sir, can i know what kind of transitor u use? also sir, how can i contact you. Just one more thing sir, can I know ur component in this project?

[mhdaiman-kitu]

Sir can I know ur component this project

[Technical_Onkar]

Hi sir
Your code is not working in JSON .6 ver

[riyasingh]

Sir how can I contact you for the project information
