About this project

IR Wireless Underwater Communication System

Objective: Create an IR-based wireless communication system capable of transmitting data underwater.

Context: Underwater data transfer is challenging due to water's attenuation of radio signals, impacting applications like environmental monitoring and underwater robotics in India's rivers and reservoirs.

What you'll build: You'll design waterproof IR transmitter and receiver modules using Arduino UNO, implementing optoelectronics for signal modulation and encoding/decoding circuits for data integrity. The system will be tested for range and reliability in submerged conditions, focusing on robust signal processing and enclosure design.

Deliverables: Demonstrable underwater communication prototype and a concise report detailing system design, testing, and results.

Milestones
1.
No submission required for this milestone.
2. Design of waterproof IR communication module
5 marks 5d
Design and submit detailed schematics and a parts list for a waterproof IR communication module suitable for underwater use. Include enclosure specifications, sealing methods, and justification for chosen IR components. Your design should demonstrate clear strategies for preventing water ingress and maintaining signal integrity underwater.
3. Data encoding system
5 marks 5d
Develop and document a data encoding protocol optimized for IR transmission underwater. Submit protocol diagrams, encoding/decoding logic, and sample data frames. Your encoding system should address error detection and be tailored to the constraints of underwater IR communication, with clear rationale for your choices.
4. Receiver signal processing
5 marks 5d
Implement and submit the receiver's signal processing algorithm, including code and a flowchart. Demonstrate how your system reliably detects, decodes, and validates incoming IR signals in the presence of underwater noise. Provide test results showing accurate data recovery under simulated interference.
5. Range and signal testing underwater
5 marks 5d
Conduct and report on underwater range and signal quality tests using your IR module. Submit a test plan, raw data, and analysis of signal strength, data integrity, and maximum reliable distance. Your results should identify operational limits and include annotated photos or videos of the test setup.
6. Final system demonstration
15 marks 5d
Demonstrate the complete IR wireless underwater communication system in a live or recorded session. Submit a video showing successful data transmission and reception between modules underwater, with commentary on system performance and any observed limitations. Include a summary table of achieved specifications versus initial design goals.
7. Advanced Footstep Power Generation System using RFID for Charging
15 marks 5d
Design and prototype an advanced footstep power generation system integrated with RFID-based charging for the IR module. Submit schematics, photos/video of the prototype, and a technical explanation of power output and charging process. Demonstrate successful energy harvesting and wireless charging of the IR system, with measured performance metrics.
