This document provides an overview of internet of things (IoTs) and how they work. IoTs allow interconnection between devices through the internet to share and transfer data. Examples include connecting home appliances like AC units and security alarms to smartphones for remote control. IoTs use sensors to collect data like temperature and humidity which is sent to gateways and then to the cloud for analysis and storage. This allows for automation and remote monitoring and control of devices to make tasks more efficient. The future of IoTs is promising as more devices become connected, with estimates of over 80 billion connected devices by 2025.

things(IOTs)

2. Overview
• Imagine you are at work and suddenly you
remember that you forgot to turn off your AC
• Instead of going back home, you can use your
smartphone to turn off the AC
Is it not amazing?
Well yes!
This can be achieved with the help of IOTs
Now because of IOTs all appliances can be
connected to the internet and are controlled
remotely

3. Internet of things
(IOTs)
• IOTs are a system of interrelated devices
connected t the internet to transfer and
receive data from one to the other.
Example: smart home
• Home appliances like doorbells water
heaters and security alarms
• All these data can be interconnected to share
data with the users over the mobile location
Until recently the internet helps people
interact and communicate with each other
but now IOTs have the ability to interact
and collaborate with one another.

4. IOTs example
• In the morning when your alarm rings the
IOTs can open the windows turn on the
coffee cup for you and even turn on the
water heater.

5. IOTs devices
General devices
• Are the main components of
the data hub and information
exchange
• They are connected either by
wire or wireless interfaces
• Home appliances are classic
examples of general devices

6. • It includes sensors and
accelerators
• They measure the
temperature, humidity, light
intensity
Sensing devices:

7. • These IoT devices are connected to the network
through gateways that process the information
collected from sensors and transfer it to the
cloud.
• The cloud access both the storage and
processing units
• Wire and wireless interfaces like WIFI, and
Bluetooth are used to provide connectivity to
ensure any ambiguity.
Working of IOTs

8. To help you understand its works, let’s take a
simple scenario
• Let’s suppose you want to water your garden,
every time the moisture level in the soil is
lower, instead of doing it manually you could
automate using IOTs sensors and accelerators
to start hitting the soil for its moisture.
• This information is sent to the IOTs gateway,
with the help of communication protocols like
MQTT and HTTP
Working on IOTs

9. • The gateway significantly advocated data and
feeds it to the cloud with the help of WIFI
• Once the moisture level drops the system
immediately starts and the fountains are
turned on
• The data analysis like the time and date on
which the fountains turn on can be done and
the report can be sent over to your
smartphone.

10. Today IOTs are being used extensively to lessen the
burden on humans
• IOTs are used in smart homes
• Wearables watches and bracelets
• Smart cars
• Smart farming
• Smart city
• Smart healthcare
With such a wide spectrum of applications, the future
of IOTs looks more promising than ever before.
IOTs Applications

11. • In 2018 there were about 23
billion connected devices which
was more than double the total
population
• According to experts, there
would be over 80 billion devices
by 2025
• IOTs is a vision to connect all
devices with the power of the
internet, always learning and
always growing
Facts

12. Conclusion
The integration of IOTs with other technologies like cloud computing,
machine learning, and artificial intelligence is paving the way for many new
and exciting innovations, and that is the IOTs for you inshort

13. Questions & answers
Which of the following technologies is not used as an interface for a
network?
a) WIFI
b)Ethernet
c) Zigbee
d)VPN
