Low-cost System for Transmitting and Receiving Data by 433MHz Wirelessly for Educational Purposes

Abstract

The concept of project-based learning is very popular among students as it allows them to solve problems and gain the necessary skills to design and implement wireless communication systems. However, it can be very challenging to implement and operate a system due to its high cost and closed architecture. This model uses project-based learning methodology to teach students how to design and construct wireless communication systems. It is a good study case for those pursuing their undergraduate degrees in electrical and electronic engineering. During the course, the students exhibited a lot of interest in the tool. This is due to the various theoretical and practical issues that are covered in the lectures. The project-based learning method is designed to prepare students for the job market by equipping them with the necessary skills and knowledge to make informed decisions. In this study, a simple wireless communication system is designed and implemented. That has ability to transmit and receive data in various ranges and environments to enhance the learning process of undergraduate students in the field of communication. Considering the length of the antenna and the environment (in/out door) the range of transmission and receiving data can be extended clearly in reality.
