4. History
oThe term “ Internet of Things” was coined in the late 1990s by
entrepreneur Kelvin Ashton in a presentation he made at Procter
& Gamble (P&G) in 1999.
o Ashton, who’s one of the founders of the Auto-ID Center at MIT,
was part of a team that discovered how to link objects to the internet
Through an RFID tag.
o Linked the idea of RFID in P&G’s supply chain to the
Then –red-Hot topic of the internet.

5. Definition
oThe Internet of Things (IOT) is Internet of Everything (IoE)
oThe Things of internet (IOT) is the network of all the web-enabled
Device that collect, send & act on data they acquire from their
Surrounding environments using embedded sensors, processors
And communication hardware.

6. Technology trends that shapes ,,,,IoT
1. Miniaturization of device
2. Sensor Technology
3. IPv6
4. IoT Gateways
5. Cloud Technology
6. Real time analytics (Big Data)
7. Improvements in communication through put and
latency
8. End User Mobile apps

7. the size --cost of electronic components
for sensing and control mechanisms.
Moore's Law of doubling transistor
density every 2 years is becoming True.
Just as the size of the chips getting
smaller, the costs of become more
affordable,
Miniaturization of Device
Most Technology components such as
radio, Wi-Fi, sensors and GPS, could see a
drop in cost of 15% to 45%. From 2010-
2015

8. Sensors Technology
IoT Sensors are used for optical, ambient light, Temperature, Pressure,
Inertia, Humidity, proximity, gesture, touch and finger print sensing
Applications.
Temperature Sensor
Accelerometer
Pressure Sensor

9. IPV6 ?

10. IoT Gateways
An IoT gateway is a centralized hub that connects IoT devices and
sensors to cloud-based computing and data processing. Modern
IoT gateways often allow bidirectional data flow between the cloud
and IoT devices.

11. Cloud Computing
The role of Cloud computing in Internet Of Things (IoT)
Cloud computing enables companies to store, manage
and process data over cloud-enabled platforms
providing flexibility, scalability and connectivity.

12. Wireless Technology

13. IoT Architecture

14. Sensor Layer
Lowest Abstraction Layer
Incorporated to measure physical quantity.
Interconnects physical & Digital world.
Collects & Process the real time information.
Example of Sensor interface:

15. Gateway & network Layer
Robust and high performance infrastructure .
Support the communication requirements for latency, Bandwidth &
Security.
Allow multiple organizations to share and use the same network
indigently .
Below open source boards like…..
Raspberry Pi beagle bone black Intel Galileo

16. Management Service Layer
Capturing of periodic sensor data.
Data analytic extracts relevant information from massive
raw data.
Stream analytics (process real time data)
Ensure Security and privacy of data.

17. Application Layer
Provides a user interface for using IoT different application for various
sector like Transportation, Health care, Supply Chain, Retail, etc.

18. Challenges…!

19. Philips Hue Light ( The Perfect Example)

20. IoT Cloud Platforms

21. Allows IOT devices to remotely control over the Internet, thus it
creates opportunities to connect directly and integrate the
physical world to the computer-based systems using internet
and sensors.
The major benefits for IoT are:
Improved customer engagement
Technical optimization
Reduced waste
Benefits of IoT
