One of the problems that I've noticed in the previous iteration of this course is that the moisture
sensor that are used that corroded very quickly once it was inserted into the wet soil.
So within a couple of weeks, the electrodes started to corrode.
Then, of course, the sensor stopped working.
So I found a better moisture sensor for the soil, which is this one.
This is a capacitive moisture sensor.
This particular model is from Sage Studio and I used that to replace the original sensor.
I don't need this component anymore, which is just the amplifier because everything now is on the same
unit and it's using a groove connector, which means that I use jumper ways to connect it to my PC be
bought here.
That was one issue.
That was the quality of the sensor that I originally used that wasn't good enough.
And now this capacitive sensor is much longer lasting.
So I'll be using this going forward.
Another problem that I had was just the jars full of soil with soil on my desk.
It just wasn't a very easy set up for me to to work on this project.
So I decided to go with an alternative.
Remember that all all I need to do here is to just take measurements from moisture sensor, solar moisture
sensor.
So I went into the kitchen and got a couple of sponges.
They are you can put a little bit of moisture in them.
Just a few drops of water would be enough.
Then create a sandwich, use a rubber band to keep two sponges together and insert the moisture sensor
in like that.
And that's basically it.
That's enough now to provide me with all the sensing and data that I need in order to work on my note
read flows.
And you can see that as I was inserting and removing and then putting back the sensor into my sponge,
did free set up the widgets in my dashboard or reactor putting green.
So for any new lectures that I record from this point on which and now in January 2022, right after
I upgraded my node change instance to version 2.15, I will be using this set up for my experiments
instead of the jar full of dirt that I used previously.
