The project is one where I want to monitor and log

  • Soil pH
  • Soil moisture
  • Room Temp
  • Room Humidity

Shown in the diagram are:

Capacitive soil moisture detector 3.3-5.5V link

ADC1115 to convert soil moisture sensor data link

DHT11 Temp/Humidity Sensor 3.3V link

Elegoo 8ch relay link

2 Peristaltic Pumps 12V link


My wiring attempt:

Gardening project

Thanks for your help, very new to this, but am enjoying the learning process!

I think you've gotten some good feedback in the comments, but your question about the correct connection or wiring isn't likely to get an answer - at least not a complete one. I say this for two reasons:

  1. It seems unlikely that anyone will have experience with each of the sensors you've selected

  2. If they did, the answer would be tedious

In other words, your question is very broad.

I'd suggest that you approach this on an incremental basis: Connect one sensor, write some code, test & verify correct operation. If you have problems, than ask a specific question re that one sensor (wiring or code or even both).

So - this isn't an answer at all - it's only a suggestion. Also, I've up-voted your question... not because it's a good question (I do feel it's too broad), but because I'm contemplating a similar project, and I appreciated the links to the different sensors.

Just one other suggestion, and I'll leave you to something more productive :) You can answer your own question here at SE. As you work through this project, you could even post multiple answers covering different aspects. Just a thought...
