Abstract: In this paper, underwater wireless (acoustic) communications system is described that leads to the design and development of a small, inexpensive system on the basis of a low frequency, single-directional piezo electric transducer to communicate via webpage. An 8-bit microcontroller and a piezo transducer were used to encode data into an acoustic wave that was transferred through water and detected by another microcontroller that used an identical piezo transducer as a microphone. It is capable of delivering throughput up to 200 bps within 1-3 KHz band. It is a versatile platform that may be used in a range of circumstances and includes real-time channel characteristics to improve communication. During operation, the system can be modified as needed by changing its implementation on the microcontroller. A 12-bit DAC is used for signal generation through transmitter. With its ADC and FFT-based architecture, the receiver has a variety of unique features and enhancements.

Keywords: underwater acoustic; piezo transducer; microcontroller; digital to analogue converter; DAC; analogue to digital converter; ADC; FFT; Arduino.
