What is IoT?

What is IoT?
Internetworking of devices, physical objects embedded with sensors, actuators,
software, electronics, network connectivity that enables these objects to collect
and exchange data.
In simple terms :
Network of physical objects or “things” which are interconnected via “internet”

Brief History of IoT
● 1990: 1 Internet connected toaster
developed by John Roomkeyst
● 1999: Term IoT was coined by Kevin
Ashton (Father of IoT).
● 2000: LG announces it’s first Internet
Refrigerator Plans.
● 2008-2009: The IoT was “Born”

Cycle
4 ACT
Taking Action based on the
Information and Data.
3 ANALYZE
Creating Information from the
received/collected Data.
2 COMMUNICATE
Sending Data and Events through
Network to some destination.
1 COLLECT
Devices and Sensors are
collecting Data everywhere.
The IoT

How IoT works?

How IoT works?
The entire process starts with the devices themselves, such as smartphones,
digital watches, electronic appliances which securely communicate with an
internet of things platform.
IoT platform collects and combines data from multiple devices and platforms and
applies analytics to share the most valuable data with applications to address
industry-specific needs.

Why IoT?

Why IoT?
● Cutting Edge Technology
○ 50 Billion connected devices by 2025.
○ “What was the last piece of technology you purchased that didn’t have Wi-Fi or Bluetooth built
in?
● Total transparency is available with lesser inefficiencies and greater quality.
● Without human intervention, the machines are able to communicate with each
other leading to faster and timely output.
● More information helps making better decisions.

Why IoT?
● Monitoring.
● Saves Money.
● Saves Time.
● Automation on Daily Tasks.
● Better Quality of Life.

IoT Technology

IoT Technology
● Bluetooth
○ important short-range IoT communications Protocols / Technology
● Zigbee
○ ZigBee is similar to Bluetooth and is majorly used in industrial settings.
● Z-Wave
○ Z-Wave is a low-power RF communications IoT technology that primarily design for home
automation for products such as lamp controllers and sensors among many other devices.
● Wi-Fi
○ WiFi connectivity is one of the most popular IoT communication protocol

IoT Technology
● Cellular
○ Any IoT application that requires operation over longer distances can take advantage of
GSM/3G/4G cellular communication capabilities.
● NFC
○ NFC (Near Field Communication) is an IoT technology. It enables simple and safe
communications between electronic devices, and specifically for smartphones, allowing
consumers to perform transactions in which one does not have to be physically present.
● LoRa Wan
○ LoRaWAN is one of popular IoT Technology, targets wide-area network (WAN) applications.

IoT Protocols

IoT Protocols
1. Constrained Application Protocol (CoAP)
2. Message Queue Telemetry Transport Protocol (MQTT)
3. Advanced Message Queuing Protocol (AMQP)
4. Data Distribution Service (DDS)

IoT Hardware

IoT Hardware
● Hardware Components
○ Arduino Micro Controllers
It is basically smaller board that is plugged into mainboards to improve and increase its functionality by
bringing out specific functions or features
○ Raspberry Pi
It is a very affordable and tiny computer that can incorporate an entire web server. Often called “RasPi,” it has
enough processing power and memory to run Windows 10 on it as well as IoT Core.
○ Beagle Board
BeagleBoard is a single-board computer with a Linux-based OS that uses an ARM processor, capable of more
powerful processing than RasPi.
○ Intel’s Galileo
It's the first board based on Intel® architecture designed to be hardware and software pin-compatible with
Arduino shields designed for the Uno R3.
○ Edison boards
It is a computer-on-module that was offered by Intel as a development system for wearable devices and
Internet of Things devices.

IoT Hardware
● Building Blocks of IoT Hardware
○ Thing
The asset you want to control or monitor.
○ Data Acquisition Module
Acquire physical signal and convert to digital.
○ Data Processing Module
The “computer” to process data, perform analytics, store data locally, and other edge
computing.
○ Communications Module
Communicate with 3rd party systems, either locally or in the cloud
● IoT Sensors
● Wearable Electronic Devices
● Basic Devices

When someone says, IoT is all about Hardware :|
I be like:

IoT Software

IoT Software
● C Language
○ C programming language has its roots in embedded systems—it even got its start for programming telephone switches.
● C++ Language
○ C++ is the object-oriented version of C, which is a language popular for both the Linux OS and Arduino embedded IoT
software systems.
● Java
○ JAVA is more portable. It is more like a write once and read anywhere language, where you install libraries, invests time
in writing codes once and you are good to go.
● Python
○ Python is an interpreted language, which is, easy to read, quick to learn and quick to write. Also, it’s a powerhouse for
serving data-heavy applications. Its use is slowly spreading to the embedded control and IoT world—specially the
Raspberry Pi processor.
● B#
○ B# was specifically designed for embedded systems, it’s small and compact and has less memory size.

IoT Software
● JavaScript
○ JavaScript is a very event-driven language, and this makes it ideal for reacting to new data from devices and triggering
actions on the devices themselves.
● Data Collection
○ It is used for data filtering, data security, sensing, and measurement. The protocols aid in decision making by sensing
form real-time objects. It can work both ways by collecting data from devices or distributing data to devices. All the data
transmits to a central server.
● Device Integration
○ This software ensures that devices bind and connect to networks facilitating information sharing. A stable cooperation
and communication ensure between multiple devices.
● Real-Time Integration
○ the input from users serves as potential data for carrying out real-time analysis, making insights, suggesting
recommendations to solve an organizations problems and improve its approach.
● Application and Process Extension
○ These applications extend the reach of existing systems and software to allow a wider, more effective system. They
integrate predefined devices for specific purposes such as allowing certain mobile devices or engineering instruments
access.
