IoT
Imagine you're at work and realize that you might not have
turned off the air conditioner while leaving your house instead of traveling
all the way back home. What if you could use your smartphone to know the status
of your AC and perhaps even turn it off wouldn't that be amazing well, yes and
we can achieve this with the help of the internet of things? Until recently, it
limited access to the internet via devices like desktop tablets or smartphones.
But now, with IoT, it can connect all appliances to the internet and monitored
remotely. IoT is shaping the way we live our lives it helps us get a better
insight into the working of things around us.
What exactly is the internet of things?
IoT is a system of interrelated devices connected to the
internet to transfer and receive data from one to the other. A smart home is
the best example of IoT home appliances like the AC, doorbell thermostats,
smoke detectors, water heaters, and security alarms that interconnect to share
data with the user over a mobile application the user can.
Now get detailed insight into the working of the surrounding
devices to think about it. Until recently, the internet helped people connect
and interact with each other, but now inanimate objects or things can sense the
surroundings to interact and collaborate with one another. For example, in the
morning when your alarm goes off, the IoT system can open the window blinds,
turn on the coffee pot for you, and even turn on the water heater. Although all
this is fascinating, there's a lot that goes on in the background to ensure
seamless functioning from effective communication between devices to accurate
processing of the data received a lot of components are involved.
In IoT devices, having hardware is classified into general
devices and sensing devices. The general devices are the key components of the
data hub and information exchange and are connected either by wired or wireless
interfaces home appliances are a classic example of such devices.
The sensing devices, on the other hand, include sensors and
actuators that measure the temperature-humidity, light intensity, and other
parameters. It connected these IoT devices to the network with the help of
gateways.
These gateways or processing nodes process the information
collected from the sensors and transfer to the cloud. The clouds act as both
the storage and processing unit actions that perform on the collected data for
further learning and inferences wired and wireless interfaces like wi-fi,
Bluetooth, ZigBee, gsms, and so on. They are used to provide connectivity to
ensure its ubiquity applications, need to support a diverse set of devices and
communication protocols from tiny sensors capable of sensing and reporting the
desired factor to powerful back-end servers that are utilized for data analysis
and knowledge extraction.
With the improved response monitoring and analytical
capabilities, IoT is being adopted in almost all industries and domains,
opening doors to endless applications. Today, IoT is being used extensively to
lessen the burden on humans, to name a few IoT is deployed for smart homes,
wearables watches and bracelets, smart cars, smart farming, smart retail, smart
grids, smart city, and smart healthcare with such a wide spectrum of
applications
Now coming to IoT as a carrier, well these are among the
four most important reasons you should consider IoT to be your carrier.
The first thing is that it is among the top 10 jobs in this entire decade. It was in the top 10 jobs for the last decade, and it has been projected. It's going to remain in a higher spot at this decade as well.
Now coming to business requirements in
today's world, everyone wants their problems to be solved at the quickest. With
respect to IoT, there is this demand and supply created where the demand is high
while supply is less and just for this one reason, if you jump on the IoT
trend, you can make a very good carrier out of it.
And of course, we live in the mobile era right, so for 80%
of our tasks during the entire day, we look at our Mobile's for its speed
browsing the Internet, beat ordering food, beat our getting into a meeting
whatever it is so we are in the mobile era. So we are a generation of mobile
users who are basically achieving goals and feats which could have not been
done probably 10 years before now anyway 20 years ago. This would have just
been fiction, right?
And of course, another important reason is that IoT is a
one-stop solution to everything beat its recycling, beat green energy, beat
your health monitoring, beat it smart cycles, beat it your working environment being
smart beat power-saving whatever it is, so we can go on and name an unlimited number of applications. Why IoT should be a very good career path for you and,
of course, it is an amazing career path.
BUILDING BLOCKS OF IoT
IoT works on five main principal components:
Hardware comprises all these sensors, the actuators, and everything which forms the actual device. This is the part of the sensing layer, which means check out in the software's architecture.
Then you have to talk about software you will write custom
code and custom programming concepts where you'll be helping this hardware talk
to the internet.
If you have to make a software talk to the internet, you
actually, need access to the Internet and this is where there's the protocol the layer where you'll be actually making your software and hardware connected to
each other.
Then, when you think about it, when you're on the internet
you need some security. So defining security protocols to ensure that your
software, your hardware, and in fact the entirety of your IoT device is safe.
The security protocols are very much important.
And then your device is ready now you need to control this.
To control all this, you can make use of your computer, you can make use of
your mobile and anything that's connected to the Internet can have access to
this.
What are the interactions that go on in the world of IoT?
So the first thing is basically people-to-people interaction
where a couple of people are sitting together deciding on the goal deciding on
what needs to be done, what is the task at hand, what is the problem at hand
and how they can solve it.
After this, people do computer interaction, it happens where
a person is an IoT developer, and he's programming the hardware to talk to the
software. There will be another software engineer whole collaborate with this
hardware programmer and so the end of the day or your people's computer
interaction is all about making your IoT device are ready and be ready to connect
to the internet.
And after that comes the Machine and the data interaction. About machine and the data interaction, your IoT device or your programming the arena must have the capability of processing data, pre-processing data, analyzing data, and even storing data.
So after all this, there comes your data
machine interaction where you know your data is offered into your IoT device
and, for example, it might not be data being fed into IoT devices well it
can be the data from the IoT device where it's a reporting and generating data
for you too.
So these are the four main important interactions that take
place in the world of IoT is key and understanding how one can go from the first stage of generating a plan creating a device, all the way to ensuring that
your data and your machine can talk to each other.
