O Level Syllabus Paper (3): Introduction to Internet of Things(IoT) and its Applications

Introduction of Internet of Things(IoT) and its
Applications

The module is designed to equip the students to understand the basics of a connected world that is Internet of Things (IoT) and its applications. IoT primarily refers to the connected and smarter world having physical and virtual objects with some unique identities. IoT applications spans across domains of industrial control, retail, energy, agriculture, etc. According to experts forecast, IoT ecosystem will have 50 billion devices/things by 2020. This module provides the theoretical and practical aspects of interfacing sensors and actuators, making an informed world of Things speaking to each other. The different type of communication modes and models are discussed in detail. The in-depth knowledge of software and packages is provided to make applications in IoT paradigm.
