IoT
What is IoT
• IoT- Internet + Things
• Internet connected people through computers
& mobiles
• Interaction using video calls, emails, livechat
social media etc.
• As development goes on, it is thought that can
we connect everyday things also with internet
like car, watch, light, TV, oven, AC, etc.
IoT
Contd.
• Network of physical objects (things) /
everyday things embedded with electronics,
software, sensors, and network connectivity,
which enables these objects to collect and
exchange data without human intervention.
• Objects send data wirelessly to other devices
in real-time and are controlled remotely
across the network.
Smart Home using IoT
Smart Home
• A simple example of IoT is smart home- an
internet connected system of devices. A mobile
app controls these devices.
• AC, refrigerator, fans, lights, TV, smoke detectors,
cameras, door locks etc. are connected to the
mobile & can be controlled.
• Instead of human communicating directly with
specific devices, in IoT the devices “talk” amongst
themselves.
Video
• Video on Smart Home
History
History
• 1982 – Students of Carnegie Melon University
developed mechanism for their campus Coca-
Cola vending machine to report through a
network if the machine was out of Coke.
• They also installed micro-switches into the
machine to report how many Coke cans were
available and if they were cold.
Contd.
• 1999- term IoT was used by Kevin Ashton
• 2000- LG launched Internet refrigerator
• 2004- Microsoft came up with first Smart
watch
History
Contd.
• 2007- Apple launched first Smart iPhone
• 2009- Google’s driverless car was launched
• 2014- Amazon’s Echo (Alexa) was launched
• 2014- Tesla’s Autopilot- driver assistance
system
Components of IoT
IoT Devices
Contd.
• Things or devices- are fitted with sensors or
actuators that collect, emit and transfer data
over the network.
• For eg. Temperature, Pressure, Humidity, Light
intensity, Proximity, Level sensors, cameras,
etc. (sensing units) are used to detect these
physical quantities and collect data.
Contd.
• For wireless data transmission to next stage,
we need a complete sensor node instead of
just a simple sensing unit.
• Sensor node- processing unit, communication
unit, storage unit, etc along with sensing unit.
• Small sized & low powered nodes.
• Nodes can talk to each other.
Contd.
• Actuators work opposite to that of sensors.
• They receive a signal or a command and on its
basis they cause an action.
• They are required to act based on the trigger.
• For eg. as soon as sensors detect that a person
has exited an area, the actuator will be
triggered to stop the air conditioning or the
flow of water in a tap.

Gateway
Contd.
• Gateway- A centralized hub that connects IoT
devices to Cloud.
• Large amount of raw data is available from these
sensor nodes.
• High speed bi-directional gateway is required to
transfer data to cloud for processing (Cloud
computing).
• Cloud is a large network of remote servers that
operate as single ecosystem. It stores data &
Application softwares.
Contd.
• If devices are not able to communicate, then
Gateway provide necessary translation.
• It acts as a single point of contact for all devices
(sensors & actuators) for interaction with cloud.
• To speed up the process data filtering & pre-
processing is done by Gateway to reduce the
volume of cloud. (Intelligent Edge) Gateway
processes small task & give commands to
actuators

What is Cloud ?
Cloud
• Cloud- Large network of remote servers &
storage that supports IoT devices and
applications. It stores data & Application
softwares.
• Gateway sends data to cloud through internet.
• Data processing - “the collection and
manipulation of items of data to produce
meaningful information.”
• Raw data into something useful like text files,
charts, spreadsheets, or images.
Contd.
• Data processing- can be very simple like checking
that the temperature reading is within an acceptable
range.
• Or very complex, like identify objects in video or read
car’s number plate in a image using computer vision.
• This is done by different data manipulation
techniques such as validation, sorting, classification,
calculation, interpretation, organization and
transformation of data.
Contd.
• IoT cloud provide connectivity, security,
scalability, ease of integration, and better IoT
device management.
• These platforms also help us to improve the
usability of our IoT app.
• Some of the commercially available IoT cloud
platforms are from Amazon, Microsoft,
Google, IBM, Oracle, Bosch, Cisco, GE, SAP,
etc.
Analytics
Analytics and Data Management
• Analytics is used to make sense of the vast
amounts of data.
• For eg. determination of key performance
indicators like deviations, errors or
irregularities in real-time.
• After that, an immediate action would be
required to prevent any undesirable scenario.
• Deep learning can be used for predictive
analysis.
Contd.
• Various techniques can be used to predict
trends, plan ahead and make useful business
decisions.
• Analytics requires large storage and intelligent
computation to be able to make sense of any
data.
User Interface
User Interface
• User interface is the visible component that is
easily accessible and in control of the IoT user.
• After processing, application software or app
gives user an alert, notification, live trends
and remote control (switching on / off).
• Touch interfaces, use of colors, voice, and
more. An attractive design is necessary, user-
friendly enough to avoid any difficulty for the
user.
IoT Architecture & Protocols
Advantages of IoT
• Minimises human effort, save time and
money
• More automation (better control)
• Improves Technology (artificial
intelligence, driverless car, etc.)
• Reduce waste, uses natural resources
effectively
Contd.
• Real time information
• Decision making by seeing the behaviour
or the pattern of events
Disadvantages
• Security issue (loss of confidential data)
• Prone to network attack
• Maintaining privacy is a challenge
Applications
Healthcare
Contd.
• Healthcare (Life saving)-
– Heart patient wearing a bio sensor wrist band is
continuously sending data related to BP, heart
rate, temperature, etc. to the hospital’s cloud.
– Suddenly at midnight, he gets a heart attack.
– Wrist band sends alert to hospital.
– After verifying the condition of patient, hospital
sends an ambulance and does all arrangements
