Realization of Free Space Optical Communication

Free Space Optical (FSO) communication is a wireless method that sends data via air using light. This paper describes the integration of a FSO communication system that is powered by solar energy. The transmitter and reception ends of the experimental setup are composed of an Arduino Uno board, a laser, and a solar panel, respectively. The goal of this study is to demonstrate the viability and efficiency of an FSO communication system that uses a laser and a solar panel. In the proposed FSO communication system, the microcontroller modulates and demodulates the data transmitted over the light beam and manages the laser and solar panel. Using an Arduino and a solar panel simplifies the system's design, lowers costs, and consumes less energy. According to test results, the system can reliably transmit data up to a distance of 10 meters with low bit error rates (BER). The proposed system is an attractive alternative to current FSO communication methods, which can be costly and cumbersome due to their complexity. The results of the experiments show that the proposed system can achieve dependable communication over short to medium distances, offering a promising wireless communication option in situations where conventional communication technologies are not practical. This paper demonstrates the implementation of an FSO communication system using a laser and solar panel, as well as its viability, effectiveness, and some of the potential industries it might be utilized in, such as healthcare, transportation, and telecommunications.
