After successful completion of this chapter, the students be able to: Explain IoT Elaborate the advantages and disadvantages of IoT Explain how IoT works? Explain the architecture of IoT Describe IoT tools and platforms Describe IoT application in different sector

1. Chapter Four
IoT
What is IoT?
● is the network of physical objects or
"things" embedded with electronics,
software, sensors, and network
connectivity, which enables these objects
to collect and exchange data

2. IoT
Internets of people Internets of things

3. IoT?
● It also defined as the internet of everything:
● Is interaction of everyday object’s through the Internet that enables the
sending and receiving of useful data
● IoT= Services+ Data+ Networks + Sensors

4. IoT features
 Artificial Intelligence: makes it smart.
 Connectivity: enabling technologies for networking
 Sensors: make it actively integrate with the environment.
 Active engagement : makes the connected technology, product, or services to active engagement
between each other.
 small device use: to deliver its precision, scalability, and versatility.

5. • It has not been around for very long, however there were inventions of technology
that provide the milestone for the IoT:
• 1800 attempt to communicate a machine with another one.
• 1830 development of Telegraph.
• 1900 “wireless telegraphy,” the first radio voice transmission took place
• 1950s development of computers .
• Global Positioning Satellites (GPS) became a reality started in early 1993,
• IoT was officially name in 1999.
• For the first time the concept of an Internet of Things is applied in Coca Cola
machine.
• By the year 2013, the Internet of Things had evolved into a system using multiple
technologies.
History of IoT

6. 6
 Improved Customer Engagement: transforms this to achieve richer and more effective
engagement with audiences
 Technology Optimization: improve the customer experience and also improve device use, and aid
in more potent improvements to technology.
 Reduced Waste (provides real-world information): the more effective management of resources
 Enhanced Data Collection

7. 7
 Confidential information could be hacked.
 If there‘s a bug in the system, it's likely that every connected device will become corrupted
 Difficult for devices from different manufacturers to communicate with each other (b/c of there is
no international standard)
 Enterprises may eventually have to deal with massive numbers of data.

8. 8
● Security: The system offers little control over security.
● Privacy: IoT provides important personal data in extreme detail without the user's active
participation.
● Complexity: In terms of design, deployment, and maintenance
● Flexibility: To integrate d/t IoT system with another is not easy.
● Compliance: Must comply with regulations.

● IoT Ecosystem consists of web-enabled smart devices that use embedded:
 processors,
 sensors and
 communication hardware
• the sensor data they collect .
• IoT devices share the sensor data they collect by connecting to an IoT gateway
● data is either sent to the cloud to be analysed or analysed locally.
● The devices do most of the work without human intervention, although people can interact with the
devices

11. Architecture of IoT
 Architecture of IoT devices
comprises four major
components
1.Sensing Layer
2. Network Layer
3.Data Processing Layer
4. Application Layer
 consists of hardware, software, network connectivity, and
sensors

12. 1. Sensing Layer- main purpose of the sensing layer is to identify any Phenomena in
the devices’ peripheral and obtain data from the real world .
Architecture of IoT
Types of sensors
1.Motion sensors
2. Environmental sensors
3.Position Sensors

13. 2. Network Layer - acts as a communication channel to transfer data, collected in the sensing
layer, to other connected devices using(e.g.
Wi-Fi, Bluetooth, Zigbee, Z-Wave, LoRa, cellular network)
3.Data processing – takes data collected in the sensing layer and analyses the data to make
decisions based on the result
4. Application layers - implements and presents the results of the data processing layer and
user-centric layer that executes various tasks for the users
Architecture of IoT

14. 14
● IoT can’t function without software, including middleware, known as an IoT or IoT platform.
● IoT platform is a set of components that allows developers to spread out the applications, remotely collect
data, secure connectivity, and execute sensor management.
● IoT platform manages connectivity of the devices and allows developers to build new mobile software
applications
● Is a multi-layer technology that enables straightforward provisioning, management, and automation of
connected devices within the Internet of Things and cloud technology.
● They can be used in areas of smart home, city, enterprise, home automation, healthcare or automotive, just
to name a few
IoT Tools and Platforms

15. 15
● KAA: This is an open-source IoT platform that works as a middleware to accelerate the IoT solutions
distribution procedure
● Site Where
 Facilitates the acquisition, storage, processing, and integration of device data
 uses default database storage mango DB
● Device Hive
 Provides instruments for your smart devices communication and management.
Some of IoT platforms

16. 16
● Application areas (industries) of IoT
1. Agriculture: Indoor planting(, IoT makes monitoring and management of micro-climate
conditions a reality, which in turn increases production), crop monitoring
2. Consumer Use: Smartphones, smartwatches,
3. Healthcare: (wearable technologies, Telemedicine, Headsets that measure brainwaves)
4. Insurance: (Fire alert, Water Leak Detection, Stolen car trackers)
5. Manufacturing: (Maintenance of equipment)
6. Retail: (automated reports, robot)
7. Transportation: (autonomous cars)
8. Utilities: (monitor environmental conditions such as humidity, temperature)
