O Level[M4-R5] IoT and Its Applications

(i) Introduction to Internet of Things – Applications/Devices, Protocols
andCommunication Model
Introduction – Overview of the Internet of Things(IoT), the characteristics of devices
and applications in the IoT ecosystem, building blocks of IoT, Various technologies
making up IoT ecosystem, IoT levels, IoT design methodology, The Physical
Design/Logical Design of IoT, Functional blocks of IoT, and Communication
Models, Development Tools used in IoT.
(ii) Things and Connections
Working with Controlled Systems, Real-time systems with feedback loops e.g.
thermostat in refrigrator, AC, etc.Connectivity models – TCP/IP versus OSI
model, different types of modes using wired and wireless methodology, The
process flow of an IoT application.
(iii)Sensors, Actuators, and Microcontrollers
Sensor – Measuring physical quantities in the digital world e.g. light sensor, moisture
sensor, temperature sensor, etc.
Actuator – moving or controlling system e.g. DC motor, different types of actuators
Controller – Role of microcontroller as a gateway to interfacing sensors and
actuators, microcontroller vs microprocessor, and other types of microcontrollers in
embedded ecosystem.
(iv) Building IoT applications
Introduction to Arduino IDE – writing code in sketch, compiling-debugging,
uploading the file to the Arduino board, the role of the serial monitor.
Embedded ‘C’ Language basics – Variables and Identifiers, Built-in Data Types,
Arithmetic operators and Expressions, Constants and Literals, assignment.

Conditional Statements and Loops – Decision-making using Relational Operators,
Logical Connectives – conditions, if-else statement, Loops: while loop, do while,
for loop, Nested loops, Infinite loops, Switch statement.
Arrays – Declaring and manipulating single dimension arrays
Functions – Standard Library of C functions in Arduino IDE, Prototype of a
function: Formal parameter list, Return Type, Function call.
Interfacing sensors – The working of digital versus analog pins in Arduino
platform, interfacing LED, Button, Sensors-DHT, LDR, MQ135, IR. Display the
data on Liquid Crystal Display(LCD), interfacing keypad
Serial communication – interfacing HC-05(Bluetooth module)
Control/handle 220V AC supply – interfacing relay module.
(v) Security and Future of IoT Ecosystem
Need of security in IoT – Why Security? Privacy for IoT-enabled devices- IoT
security for consumer devices- Security levels, protecting IoT devices
Future IoT ecosystem – Need of full power core for building secure algorithms,
Examples of new trends – AI, ML penetration to IoT
(vi) Soft skills-Personality Development
Personality Development – Determinants of Personality- self-awareness,
motivation, self-discipline, etc., building a positive personality, and gestures.
Self-esteem – self-efficacy, self-motivation, time management, stress management,
Etiquettes & manners.
Communication and writing skills- objective, attributes and categories of
communication, Writing Skills – Resume, Letters, Report, Presentation, etc.
Interview skills and body language.
