a brief view on introduction and working

3. The Internet of Things (IoT) is generally thought
of as connecting things to the Internet and using
that connection to provide some kind of useful
remote monitoring or control of those things.
The IoT creates an intelligent, invisible network fabric that can be sensed,
controlled and programmed. IoT-enabled products employ embedded
technology that allows them to communicate, directly or indirectly, with each
other or the Internet.

4. Just a few decades ago , people were “connected” to the world outside
their homes in very limited ways, primarily with landline telephones,
radios and televisions.
The birth of IoT:
* The term IoT was coined by kevin Ashton
•The term Internet of Things is 16 years old.
• But the actual idea of connected devices had
been around longer, at least since the 70s.
*The idea was often called “embedded internet” or
“pervasive computing”.

5. *most people became connected to the internet one way or
another.
->Devices which were not originally designed for internet
connectivity began to go online, such as vehicles, watches,
refrigerators, washing machines etc

8. Things &Devices
*Devices and sensors are the components of the device
connectivity layer.
* Smart sensors are continuously collecting data from the
environment
Common sensors are:
*Temperature Sensors
*Pressure Sensors
*Humidity sensors
*Proximity Sensors
*level Sensors

9. Humidity sensors Pressure sensors Speed sensors
Traffic sensors Water level sensors Temperature sensors

10. How the devices are connected?
•connected to low power wireless networks
•Wi-Fi, ZigBee, Bluetooth, Z-wave, LoRAWAN etc…
*wireless technologies has its own pros and cons in terms of power, data
transfer rate and overall efficiency

11. Gateway
*manages the bidirectional data traffic between different networks and
protocols
*translate different network protocols
*pre-processing of the collected data
*Acts as a middle layer between devices and cloud
*protect the system from malicious attacks and unauthorized access.

12. Cloud
*integrates billions of devices, sensors , gateways, protocols.
*Offers tools to collect, process, manage and store huge amount
of data in real time.
*Provides services like SaaS ,PaaS, IaaS
*high speed data processing of billions of devices
*traffic management , deliver accurate analytics and
distributed database management systems

13. Analytics
User interface
*Future business opportunities.
*predict trends in the market and plan
ahead for a successful implementation.
Native Apps
Web Apps
visible, tangible part of the IoT system

16. Real World Applications of IoT
-> Smart Home
-> Wearables
-> Connected Cars
->Industrial Internet
->Smart Cities
->agriculture
->Smart Retail
-> IOT in Healthcare
->IoT in Poultry and Farming

17. Consumers already have connected things like thermostats, energy meters, lighting
control systems, music streaming and control systems, remote video streaming boxes,
pool systems, and irrigation systems with more to come. Most of these systems have
some connectivity through a Web site so that a user can manage them through a
standard Web browser or a smartphone app, which acts as a personal NOC(network
operating centre).

20. Health , industry and agriculture

21. *There is a huge risk of leakage of confidential data.
*With automaton the need of human labor reduces drastically.
*Lifestyle become technology driven, depending on technology for
tiniest tasks
Disadvantages of IoT

22. We will witness continuous development in IoT due to huge demands in
different sectors.
->more accessible,
->cost effective,
->energy efficient
->secure.
