Hello, everyone. I hope you are wonderful and welcome to the new
course communication with iot. So this is our first
section in this section. We're going to talk about
communication Technologies and protocols.
So this is our first video video number 1.1. And
in this video, we're going to talk about iot architecture and
components.
So firstly let's talk about the history of internet
thing. So the first machine was a Coke
vending machine, which is
developed in the lab to monitor the
campus Coke vending machine stock. If there is
a low stock then it will give the notification to
fill up the Coke vending machine and the
first prototype which is
really connected to the internet which
is toaster John ramki developed that
prototype in 1990s. So this
is the history and let's talk about the future and the
current scenario right now in 2021 the
iot market.
Closed at 385 billion US dollars,
but it is projected from 478 billion
dollar to USD.
2,465 billion dollar till 2020
9 so from these figures.
we have
an
statistics that iot market is
rapidly growing and we have a vast opportunities
in that field.
So before moving on we need to talk about what is
thing? So here is a picture which is
explaining about the thing. We have a lot of
things in our real life like animals.
because motorbike motorcycle our
bulb if we see in a room,
we have a fan but light and lot of
other stuff and if we move to the industry, we have a machines and
motors equitators and
lot of other stuff so
What is meaning of thing in Internet of things
when we talk about internet of things that means
that a thing which is connected to internet where
any communication technology like Wi-Fi
2G 3G seek be Laura
van wide.
It is a thing because it connects the internet.
It contains an IP address or any communication
protocol which provides a bridge
between device and internet. So it is
a connected thing and is called a thing.
in terms of Internet of Things
So now we need to talk about the architecture and component. So
here we have four modules. The
first thing is we have a thing like for
example, we have a bulb smart bulb and the next
thing is a network which provides the connectivity and it
depends upon the scenario. We have a lot of network connectivity
options. Like we have a Wi-Fi
Bluetooth 3G 4G Laura van
sigfox that we're going to discuss in the next
sections practically. The device will be
connected to the internet where that Gateway Network
protocol and then we have a meter where
which is actually iot Cloud platforms. We
have a lot of different Cloud platforms like azure.
Amazon AWS Google sorry
Google actually stopped there Google iot
core services, but we still we
have IBM and Arduino iot cloud is an awesome
platform and easy to use.
And the next thing is application. So the
middleware is responsible to get all
the data from the devices and store into the database and
provide this tool to visualize the data
and as well as provide the apis and
webhooks to
Other applications to interface the data from Cloud to
their applications and the fourth module is application because
we have a
data on the cloud but we need to give access to
users so they can access the data control the
devices and visualize the data from
the things to get the better insights. So
there's a form module which is related
to the applications where we will provide the
graphical user interface to the user to get excess
of their data visualization. So this is the
Iot architecture, you
can manage on
the many platform middleware and applications are merged into
the one module. So then we will get the
three modules but this is the open architecture which
is applicable to different application
development.
So guys in the next video. We're going
to talk about communication Technologies versus protocol. So
see you in the next video. Have a good day, bye-bye.
