3. Abstract.
1) Water data communication is a potential technology to realize underwater
communication. The experiment of underwater data communication in the laboratory is
different with that in the real water environment because the physical scale is limited.
2) The system uses the ultra-low power MSP430F449 MCU as the control core, and uses the
infrared wireless communication, achieving a simple underwater wireless communication.
3) The entire system consists of 3 parts.
 the land-based unit.
 the electrical unit .
 the submarine model.

4. Introduction :
o system makes use of infrared transmitter receiver in order to achieve this system.
o Our system consists of two microcontroller based circuits that have IR transmitter-receiver pairs as
well as LCD displays for displaying the messages.
o Each system has a keyboard connected to it in order to type in messages.
o We use two water barrels in order to demonstrate underwater communication using IR signals
passing through those containers.
o The system also has an acknowledgement receipt message that is sent back from the receiving
circuit to the transmitting circuit on message receipt.
o This allows for efficient communication between two circuits wirelessly.

The signals that are used to carry digital information through an underwater channel
are not radio signals as electromagnetic waves propogate over short distances.
Instead acoustic waves are used which can propogate over long distances.
The infrared light detecting unit then provides a logic zero at its output when its receives a
pulsed burst of infrared radiation for time period of approximately six hundred
microseconds and a logic one when the unit fails to detect a pulsed burst of infrared
radiation for a time period of six hundred microseconds.

6. Problem statement .
1. IR based underwater communication system that can be used for
wireless communication of messages even through water. The system can
prove to be a very cheap alternative to long heavy physical wires that run
through seas, rivers and require large costs for laying those wires and
their maintenance.
2. Today, underwater sensors cannot share data with those ashore, as both use
different wireless signals that only work in their corresponding mediums. Radio
signals that travel through air die very quickly in water. Acoustic signals, or
sonar, sent by underwater devices generally reflect off the surface without ever
breaking through.

7. Problem Statement:
3). This causes inefficiencies and other problems for a variety of applications, like ocean
exploration and submarine-to-plane communication. To start, there are two selections of
underwater communications: Hardwired- uses a cable to transfer the communications;
Wireless- uses the water to transfer the communications. Many divers prefer the idea of
freely diving where they please with the ability to communicate to their dive partner easily
and quickly.
4).Wired underwater is not feasible in all situations as shown below-:
 Temporary experiments
 Breaking of wires
 Significant cost of deployment
 Experiment over long distances. To cope up with above situations, we require
underwater wireless communication. September 22, 2023 7

8. Arduino:
 Arduino (UNO Microcontroller) There are four classes of Arduino but in this system Arduino
UNO is used.
 This Arduino UNO is enough for the file transfer from one PC to another PC.
 This Arduino class has 13 digital pins, 5 analog pins and power supplies such as 5 volts and
3.3 volts.
 The LED blinks according to the binary logic sent from the processing software.
 Arduino is associate American Standard Code for Information Interchange file hardware and
computer code package company, project and user community that styles and manufactures
single-board microcontrollers and microcontroller kits for building digital devices.

9.  The board's area unit equipped with sets of digital and analog input/output (I/O) pins which will be
interfaced to numerous enlargement boards ('shields') or breadboards (For prototyping) and
different circuits. The board features serial communications interfaces, as well as Universal Serial
Bus (USB) on some models that also is used for loading programs from personal computers. The
microcontrollers may be programmed victimisation C and C++ programming languages.
Additionally, to victimisation ancient compiler tool chains, the Arduino project provides AN
integrated development surroundings (IDE) supported the process language project
 The LED is connected to one of the digital pins. The Arduino works according to the program
dumped into the Arduino.

11. Transmitter part:
In transmitter part the data is said to be transmitted by transmitting an number or word
from pc via data modulation unit and through led array.
Words/data can be converted to digital signals of 0s and 1s in data modulation unit and
provides series of pulses such that data can be converted into digital signals of binary bits.
Data gets selected from the pc which we want and is then transmitted successfully. Once the
data is transmitted it reaches receiver side through IR LED. The goal of transmitter part is to
transmit data.
Data modulated and given to LED
Receiver Part :
The goal of receiving part is to receive the data that is transmitted from the transmitted side
successfully.
Demodulation and decoding of data The data sent by transmitter is successfully received by
the receiver that is IR photo detector is detect the invisible rays coming from the IR LED.

14. Conclusion of the Project
 Optical wireless communication using infrared beams implemented in this paper support
a wavelength radiation of 90º and a distance of up to 5.6m.
 We notice that infrared offers a huge un-shared capacity to independent point-to-point
devices, with maximum power efficiency making good use of a microcomputer serial
ports for automatic encoding and decoding functions.
 The use of a simple hardware circuit was used to achieve our main objective, which
entails a low cost, uncomplicated software design, and stable performance of the system.
 We suggest that for high-speed data transfer, the baud rate can be increased.
 Also, components can be replaced or added for higher reception or faster reception
from the system setup.
 It is suggested that optical wireless communication using infrared systems eliminates the
congestion in the radio spectrum by helping to offload high capacity traffic loads,
thereby leading to a more cost-effective .
