Internet Of Things

The Internet of Things is the general concept of network devices to capture and collect data from the environment and then share that data over the internet where it can be processed and used for various interesting purposes.

IoT-based systems connect the Internet to the physical world with the help of ubiquitous sensors. Availability of low-cost sensors and long-range wireless technologies The connectivity gap has been closed.

The subject conveys basic concepts of the IOT through real-time applications and working on various microcontroller boards and hardware interfaces in order to understand practical aspects of the topic.

Topics covered include concepts of embedded, networking, sensing, communication protocols, and cloud services such as Node-Red that are intended to be connected to IOT devices. Even advanced concepts of the IOT are covered by real-time applications and case studies.

Students are encouraged to work on real-time projects in order to better understand the implementation of ideas from a hardware and software perspective.

Topics covered include concepts of security concerns in IOT systems, the role of the IOT in different domains with all possible paths, communication protocols, how AI and IOT work together, and case studies.

The purpose of this course is to provide students with a solid foundation in the fundamental concepts of the Internet of Things. The main objective of the course is to get the students to learn and implement real-time IOT applications. The course covers understanding how basic embedded devices and microcontroller and microprocessor chips work.

 Discussions about the functionality of various environmental sensors and their interfaces to microcontroller chips are covered. Basic understanding of various communication protocols and communication technologies for implementing IOT applications as well as the general concept of cloud computing and working with the IBM Cloud for device communication with the cloud are included.
