Transcripts
If you look around, you'll find at least one thing that has the
ability to connect to the internet.
It may be your phone.
It may be a laptop, your TV, or even your fridge, internet of
things generally refers to the collection of all those devices.
But now just, you can argue that anything that has the ability
to connect to the internet and collect and share data is a part of
internet of things or IOT in short.
Now the question here usually is what is Audi?
Why do we need it?
How does it help us?
How does it work in many, many more questions?
So in this video, guys, we will try to answer some of those questions.
So the first question, what is IOT?
So just as we discussed, I already IOT it first to the collection of
all those devices that have the ability to connect to the internet
and collect and share data.
Hence the name internet of things.
So basically we have a device that collects data from its surroundings,
using sensors and actuators, and sends this collected data to the internet where
the processing of that data can happen.
There are many devices that can be included in this classification.
An example can be phone laptops, watches, DVS refrigerators, washing machines.
Cars and even homes.
Yes.
Whole homes themselves can be a part of IOT too.
You can easily see the trend over here.
Most IOT devices have the word smart at the start of their names, smart
phones, smart watches, smart DVS, smart refrigerators, and smart homes.
So now that we have a clear idea of what IOT is, we can move to the next question.
Why do we need IOT?
Or how does it help us in short?
It helps makes our lives.
Easier and more comfortable.
If we take an example, we had listed earlier, like smartphones,
smartphones have more use cases than I can, you know, list here without
going on for ours and ours, it can call, it allows us to watch movies.
It allows us to connect to the internet, interact with strangers
on veered forums shop or things.
We need general entertainment.
You get the idea, but let's take a better example for our understanding.
Smart house.
A smart house has many different features that we can talk about.
One of the features is automatic lights, where the lights automatically detect
your presence in the room and get switched on, or they can be voice activated.
You can say activate and they'll get searched, John.
And it also has his name next gen security to keep your house safe, but
it allows only authorized people to enter your and locks up everything.
When you leave.
Then it has entertainment management, fair using devices, such as Google home,
Alexa echo to keep track of your chores, to play movies and songs, et cetera.
It also keeps track of temperature management, the house automatically
adjust to the most, you know, temporary too, based on the surrounding climate.
So you can see how it brings luxury into our lives and makes it
more comfortable for us to live.
Now, this is at an individual level, at a larger scale.
It benefits the society as a whole too in industries.
Such as healthcare, it has many use cases, doctor, patient interaction,
for example, it allows for remote interaction between patients and doctors.
So if a patient has any sort of a deadly disease, the doctor doesn't
necessarily have to come in close contact to help the patient out.
Another example here is that data analysis is improved greatly.
Now doctors make amazing decisions and based on the time and the data
they've been given, but computers can sometimes make better decisions.
And combining doctors and computers can give us the best diagnosis possible.
Follow patient.
So it helps us out a lot in the healthcare industry.
Farming, not farming has been one of the industries that has
stayed with us since the beginning of human civilization itself.
And right now is the correct time to improve upon our traditional methods
and shift into modern farming to provide food for our evergreen population.
Smart technologies has definitely helped us increase the productivity
through new devices like smart tractors and analysis devices.
That will help us to get a better data analysis of a soil, then
gums, manufacturing industry.
Now this industry already taken IOT with open arms.
It already has automation replacing many menial jobs.
I already even not only increase the interactivity, but also boost the
efficiency, add production as well.
In this industry then comes education industry.
Now better methods to teach children are already being implemented out
there that are in conjunction with IOT.
A good example is augmented reality.
Being used in some classes to give students a better experience of real
life animals, and even extinct animals.
Hence having IOT will not only be beneficial to us individually, but
also be beneficial to us as a society.
Then comes the next question.
How does IOT work?
Let's discuss the IOT architecture.
There are basically four layers to it.
The first layer is sensing slash device there, which is
basically the thing part of IOT.
This thing is basically the, with the device.
It has sensors and actuators that collect the data from surroundings
based on specific function.
Example, preachers, sensors, atmospheric pressure sensors, and light sensors.
They basically collect all the data and they give it to the embedded.
Device now after the data has been collected through the sensing device
layer, it goes to the connectivity layer, very descent to the cloud.
Using the internet.
This connection is generally me through one of the methods like via
Bluetooth cellular, RFID, or NFC after that comes to data processing layer.
Now the data, once it reaches the cloud is subject to the
real meat of the whole process.
That is the analysis part of the data.
The different types of algorithms are used.
Based on the type of data collected and other assumptions to get meaningful
insights and patterns, then a decision is made based on the insights gain.
Once the hard part is over the result of the decision is conveyed
to the thing or the IOT device.
And similarly changes made user interface and application.
Yeah, it's the last layer.
This is a layer that most of us will actually see.
It is a layer we used to with dietary device.
It can be the touch screen or the buttons that is on the device.
It's basically the front end to all the backend processing, which
included the previous level.
Now a good example to explain this processes, let's say
a fridge, a smart fridge.
Now sensors in the smart fridge, collect data from the surrounding.
They see what kind of temperature it is.
Let's say it's 34 degrees.
And what kind of item is being stored inside the fridge?
Once it collects all of this data, it sends it to a central
cloud where the processing happens based on this collected data.
The system decides the inside temperature of the fridge.
It should be 20 degrees and we can see the result of this on the
interactive screen, on the fridge.
Now we had no involvement in this process, but we saw the result that we wanted.
This is how IOT works in adjust.
What kind of feature does IOT have?
It would not be crazy to see that we may live in a future.
Heart Lake Howard is depicted in scifi movies, not the star or Skype, but
more like the blatant and Ironman kind.
But everything we touch on, everything we used is connected to the internet,
buried with central cloud, where all of our data is being collected
and being utilized to make a lie, Anna society a much better place.
You can assume almost everything is going to be automated and connected to
the internet, everything, your table, your phones, which are already are your
doors, your hangers, you know, examples.
And you can see that all of them are going to be a part of IRD in future.
And.
There is definitely a lot of space for growth.
So if you're thinking of a career in this field, not at all a bad idea, it
will be both satisfying and challenging DW flow from everything we use.
And it will be used to make our lives easier.
Every person, no matter what background or what profession they are from will be
affected by it in both good and bad ways, it will be, or rather it is the advent.
