🗒 Course Introduction

The educational course planned this time is an Internet of Things (IoT) communication project using the MQTT protocol .

Among the trends of the 4th industrial revolution, the Internet of Things (IoT) is developing rapidly, and various IoT-related education programs are being conducted at universities and educational institutions.

I think the core of the Internet of Things (IoT) is the communication part . Many students find the communication part somewhat more difficult than the hardware part, and I think they find it difficult because they have to implement communication in software.

In this course, you will build the entire communication process required for an Internet of Things (IoT) application. We planned this course to provide a method to create a prototype for a future project or prototype by learning the series of processes for collecting and monitoring sensor data from a software perspective.

   

Learning Objectives

① We will implement a communication process to monitor and control (LED) sensor (DHT11) data using the web, Java, and smartphone (Android) based on the Internet.

② You can prepare for contests and competitions, and design an IoT communication prototype before developing a prototype.

③ You can learn about the basic technologies that can collect and analyze various sensor data required for processing Internet of Things big data.

Project subtopics

① Controlling LED using Web and Android
② Monitoring DHT11 temperature and humidity using Web and Android
③ DHT11 temperature, humidity monitoring and LED control in Java

🙋🏻‍♂️ Expected questions related to the lecture

Q. Are there any special advantages to this course?
A. Rather than using just one technology, we designed it to integrate various functions and enable comprehensive thinking.
B. You can create an IoT communication prototype and use it directly for contests or projects.
C. You can set up a practice environment with low parts cost (12,000 to 15,000 won).

Q. Can non-majors also take the course?
A. It may be a little difficult for non-majors, but we provide a 70-page self-produced textbook and source code, so even non-majors can follow along.
B. This course is designed to help non-majors become interested in the Internet of Things.

Q. Why should I take this lecture, “Internet of Things Communication in My Hands”?
A. To become a leading workforce in the 4th industrial revolution, you must acquire communication technology.
B. Big data and artificial intelligence also need to use communications to be released as products. As such, the importance of communications technology is growing.
C. Non-face-to-face IoT products will boom due to the spread of COVID-19.
