Basic setup for a simple IoT project

[Therese Grass]

Hi!
I'm taking a 4-week summer course in IoT and the goal is to create a simple IoT project and my idea is to use a soil moisture sensor with my lopy4. Due to the fact that I'm a total beginner with no prior experience I struggle to wrap my head around the basic setup. I have tried to follow the image below and I would really appreciate any inputs you guys might have before I start it up and accidentally fry it :)
My setup:

I am also looking for the code needed for reading the sensor, any tutorials / github links? :)

Thank you!

Hi
if you use safe voltage (3.3V) it will be no problems.

So if you have choosed third pin from the top right as a power + source and second pin (as GND) it is ok.
Look only at pins of your sensors to not mix polarisation.
