Let's go ahead and do some testing.
I've got my chance with what, containing what's in the water reservoir with the pump submerged in it.
And then I've got my terrarium on the other side and I've got the hose from the pump going into the
turning from the lid, drip another couple of holes here for the wires, for the sensor and for the
hose itself.
For now, I've got my power supply for the pump turned off because I want to check the value that is
coming out of the humidity sensor for the soil so that I can do a bit of calibration there before I
attempt to turn on and power the pump.
So having a look at my readings in the dashboard, you can see that this soil humidity is now at eight
hundred and sixteen.
And that indicates like a test that the soil with my with my finger, just a very lamen type of soil
testing and it feels moist and not a gardener.
So I don't really know how much humidity or how much moisture the soil needs to have for my plan, which
is a settlement to be comfortable.
So I don't really know if I need to add more water or not.
This is not what this course is about, depending on the plan that you want to raise and maintain in
your terrarium.
A bit of reading on the topic, but for now, let's say that we actually need to get some water in there.
So I would use my pump threshold control here widget to increase the.
Setting to a number, maybe close to eight hundred, so around hearsay, so now what will happen is
you can see the pumps that, according to the flow, should be turned on.
But because no power from the power supply, the pump is not turned on.
I'm going to supply power in a moment.
So he'll go at age 17 for the humidity sensor.
The threshold is eight hundred at the pump state is on.
And because I want to test this with that actually flooding my terrarium, I'm going to use a glass.
So I am going to get the hose from the pump into my glass of water.
And see how the pump reacts to me, turning it on and providing power at the same time, of course,
the the humidity, the value will not change because I'm not getting any actual water coming into the
terrarium.
But I want to test the pump first.
OK, here we go.
I'm going to turn on power.
And see what happens.
He had to pump it to go start.
All right, perfect.
All right, so we had the pump working for five seconds, it pumped this much water in that amount of
time.
So this is how much water will go into your terrarium in the five seconds at the pump is running so
that it works.
So what I'll do next is I'm going to.
Move the hose from the pump into the terrariums.
Because I also want to see how the value that is reported by the committee since it changes depending
on how much water is being pumped in it.
So to make this work, I'm going to change the threshold to make it just a little bit higher.
Then the soil humidity, the soil community
spirit, too much, make it up to eight hundred and forty.
Make it actually slightly less to see if I can trigger the pump to start.
There's a bit of work went went through, you can see that the soil humidity dropped immediately.
All right, let's do this one more time.
I'm going to drop the threshold to a little less.
We get paid.
Five second flow and look at how fast the soil humidity changed.
It now increases slightly as the water is being is dissipating through the soil.
The.
The pump that the hose is depositing or is getting the water to go very close to where the sensor is,
so is that what is coming through the sensor that sensors that immediately and with its value drops
very quickly, but then as the water is dissipating around the soil, the humidity value increases.
OK, so I'd say that the experiment worked and you were successful, at least it gives me the indication
that everything is working as it should at this point.
So to continue with my experimentation, I will go back to my D.C. motor and the.
Consumer and get these jars of tuna the table.
