Hello and welcome to this new one, and I'll try to go going to design our circuit.
Now we will use our soil moisture sensors to measure the volume of the water content in the soil, and
we will mainly use that the HD 11 sensor, which we will use to measure temperature and humidity levels
in the plant's surroundings, and the water level sensor will measure the water level in a small tank.
And this is an optional sensor.
You can choose to add it or not, depending on your water.
Let's say state, if you have a continuous water supply, you shouldn't worry about the tank level.
Now, to design or circuit, what we need to do is simple.
We will need to open up the phrasing that we just downloaded.
Double click on it.
Now, this one simulate the real life connection, so you need to concentrate.
Go to the big board, view up here and you will see a bullet port.
Now move this aside.
We will need ESB 32, a board.
And as you can see, we have a lot of yes, people, we need ESB 32 balls this one.
OK, now we will also need a relation with you.
Now you can see that here we have a lot of really modules, active components, we will take this one.
We will need the it's 11th of DHT.
OK, let's try another.
We.
OK.
When you face this problem, when you try to address in Sudan, you don't find it.
Let's try another name.
This means that this sense of is not here.
And as you can see here, we have one of these sensors.
It's called Orexin.
And we can see that it almost have the same terminal's ground.
And you can see and that signal so we can use it for this connection.
And you can either look for alternative or you can download it online.
A lot of libraries are already available by people who are creating these components, so you can download
it and added.
But this will take a lot of time, so we will use this instead.
Now.
Now we need the soil more moisture sensors.
This is it.
We will need the water level sensor.
And when you look for it, you won't find it.
So in this case, you need to go to Google here and in here, right?
Water level sensors.
Frightening.
As you can see, you'll get water level.
OK, okay, this is our indicator, let's look for Dimostra search.
J.
I'm.
There is more than one.
Let's buy this water level.
For I think the goal, OK?
The first result is this, as you can see, this is the water level since this is the flooding that
we are going to download.
It has a water level sensor connected to Arduino, and we only need this item.
So download the files and find from here.
Here it is now to open it up.
You need to go to Fried's and.
And drop the file on your open flooding software.
You will see that now you'll have a new window.
And this is the water level sensor.
Now what you need to do is simple.
Copy and paste the sensor, and here you have it.
I'm sorry.
Oh, OK, now now let's connect these items to our ESB board.
We will start with the etch sensor.
We know that we need a ground connection, which is the black one.
And we will also need.
Five votes, so I took out five volts.
We need to make sure this V and pin will provide you with five volts.
And you need to make sure that you are, you know, what you are doing, because if you connected your
ISP board through your ISP, you will get five volts from this Villepin.
Otherwise, you have to connect an external power source that provides five volts.
Now we need to connect the first sensor with which is that the edge sensor?
Now, as you can see here, we have more than one terminal that we need to connect and depending on
the terminal that you are trying to connect.
No.
We need to connect the VXI underground.
Now the is, he must be connected here, but we need to connect.
That is die out here and the black boy out here.
Just to make sure that we have thought up there that, OK, no, the voices, he will be convicted here.
Now we have other turnarounds.
This is that other signal, and we will send it to our ESB 32 board.
Let's send it to the spin.
Kerry's been listening to Ben No.32.
So the colour to yellow.
And here we have the ground ban, and we must benefit to ground Dakar to black and this one to red.
Now, this ban is the second round, and you can connect it to the ground.
Here, depending on the module that you have, you can check that other sheet for that connection.
But this is the connection for the one that we have here now.
Now to connect directly with y'all, we can't use this one as it has a lot of input output pens and
it's a dedicated module.
So let's remove these.
I already downloaded at an individual and I'll provide a link for you to use it.
This is it.
You can drag it and Robert on your Friday thing.
And as you can see, here we have it.
You just need to drag this module and Robert here.
Now we have these three pins.
The signal must be connected to your board.
And let's choose a different color.
Let's say Green and the blast must be connected to the five volt.
The miners must be shifted to ground.
And we can't allow him to block.
And yellow.
Well, all right.
OK, now.
We come to this module, which is the water level module.
We need to connect the plus to five volts.
The Black.
To.
Background, which is the minus.
And the signal can be connected to the 21.
No.
Listen first to, let's say, all of us.
Now we have three signals.
One output and two inputs from sensors.
We also have that sensor.
Which is this one?
That's almost certain.
Now let's go to the ground.
To the ground that we see.
Lovely to see the signal to the 19.
List shows a different coloring.
And.
That's it.
I will show the colors to red.
On this one.
I will change it to black.
Now we have to make the soil moisture sensor, the water level sensor, humidity and temperature sensor
as input, and we have committed the relay as output.
I will say there's art.
Let's call it circuit design.
I will provide this circuit design and the resources so that you can get these modules for your friends
in design.
Now.
Again, make sure that you take note of all of these sensors.
Now we have thoroughly connected to the number 20 tool.
So let me open up a notepad.
OK.
Right click new.
Not bad.
Let's call it Ben's.
Now inside it, we need to make sure that we have everything now the sensor.
Is connected to the 23 who really is connected to the 22GB and water level.
This connected to the.
21 and soil is connected to the mine, you.
As you can see here, the U-19, U-21, the according to the U-23, this will be used in the recording
section.
Now you can see the schematic for your design here, as you can see.
You can't blame the these components.
And you can also make the landing.
You look out onto these items.
You can't control them so that they are connected with wires.
As you can see, fighting is trying to weigh up these components together.
As you can see here, we have a problem.
So you need to manage it with this, and you can't even create a PCB design.
By moving these components.
Or at the very least, increasing the size of this layout.
Now, as you can see, it's a piece of cake.
And you can also use.
What roads?
Click on auto route.
Will take some time.
Then you will get your PCB design ready for manufacturing.
Now there are still some areas that you need to root manually, as you can see this one.
You need to connect out from here to here manually.
And you can do the same for the rest of these wires.
And as you can see, you can then move to fabricating.
And that's it.
Thanks for watching this lesson.
If you have any question, please ask about this is optional for educational engineering.
