Good day! We are a group of beginner electronics and programming enthusiasts who are currently working on a project based on your amazing work titled "Arduino & NodeMCU Based Smart Water Quality Monitoring System using IoT" that we found on CircuitDigest.

We noticed that the complete code and some of the connection details—especially how and where to connect the temperature sensor (DS18B20)—were not clearly mentioned on the page and in our project instead of soil moisture, we're using the temperature sensor. Can we ask what to remove and where to connect the temperature sensor?
Thank you very much for your time and for sharing such a great project with the community!

 

It certainly seems a poorly documented project. You might best proceed by trying to contact CircuitDigest (which appears to be based in India) for clarification: https://circuitdigest.com/contact
