Innovative Aquaculture Monitoring System Patented by Dr K A Sunitha and Team
In a significant advancement for aquaculture technology, Dr K A Sunitha, Associate Professor in the Department of Electronics and Communication Engineering, along with her B.Tech ECE students Ms B Harshitha and Mr B Taraka Rameswara Kanaka Durga Prasad, have made headlines with their latest invention. The team has successfully filed and published a patent for “A Fully Automated System for Real-Time Monitoring of Aquaculture Environment and a Method Thereof.” The application number 202441034671, has been officially recorded in the Patent Office Journal, marking a milestone for the team and the institution they represent.
This pioneering system promises to revolutionise the way aquaculture environments are monitored by leveraging automation to ensure real-time, accurate assessments. The invention stands as a testament to the innovative spirit and dedication of Dr Sunitha and her students, who are now recognised as contributors to the technological advancements in the field of aquaculture.
Abstract
This project involves the design and development of an Automated water quality analysis system to assist aquaculture farmers. The proposed system is tailored for aquatic environments, particularly ponds to monitor crucial parameters say Dissolved Oxygen (DO), PH, Temperature and Humidity levels, signaling when concentrations drop below the predefined threshold set by the user every thirty minutes. The system features autonomous activation and deactivation of aerators to ensure continual oxygenation of water and aids in energy optimisation. Utilising advanced sensors and a microcontroller, the device offers continuous monitoring of parameters to facilitate pond operators with timely insights into water quality dynamics, enabling proactive interventions to protect aquatic ecosystems.
Brief Explanation of the Project
India is the second-largest aquaculture nation in the world, and this sector provides livelihood support to about 280 lakh people. The aquaculture industry globally faces numerous challenges, such as Viral, bacterial, and fungal diseases and Suboptimal water quality. One crucial criterion for evaluating the quality of water is measuring the Dissolved Oxygen level. Water and other liquids contain free, non-compound oxygen, which is measured as dissolved oxygen (DO).
Long-term exposure to low DO levels increases stress and infections and, in certain situations, causes the death of the organism because dissolved oxygen is essential for the health and reproduction of many fish and invertebrates. This project highlights the design of a timer based automated water quality analysis system which can be used in the inland aquaculture farms to continuously monitor the water parameters and automate the calibration process and the operation of aerators without human intervention.
Practical Implications of the Research
The main objectives of this research are
1) To monitor the parameters, say Dissolved Oxygen, PH, Temperature and Humidity levels
every thirty minutes.
2) To automate the Calibration process to maintain accuracy and reliability of the system.
3) To automatically turn ON/OFF the aerators in the event of Low/High oxygen levels detection in the pond.
4) To send notifications to the technician or farmer every thirty minutes to help them monitor.
Future Research Plans
The developed prototype is currently validated with standard DO meter during experimental trials. Moving forward, further research and development efforts may focus on refining the system’s functionality, expanding its sensor capabilities, and integrating advanced analytics for predictive monitoring and decision support, thereby advancing the state-of-the-art in aquaculture management technology and promoting the long-term viability of inland aquaculture operations.

Exploring Wire Arc Additive Manufacturing
Wire Arc Additive Manufacturing (WAAM) is revolutionizing how we make metal components, especially when it comes to materials like 304L austenitic stainless steel—a popular choice in industries such as aerospace, automotive, and healthcare due to its durability and corrosion resistance. The research paper titled “Microstructural Characteristics and Properties of Wire Arc Additive Manufactured 304L Austenitic Stainless Steel Cylindrical Components by Different Arc Welding Processes” published by Dr Maheswar Dwivedy, Associate Professor, Department of Mechanical Engineering and his post-doctoral scholar Dr B Prasanna Nagasai explores this innovative manufacturing method in detail, focusing on how different welding techniques affect the end product.
Overall, this research indicates that WAAM, with its different welding techniques, can produce 304L stainless steel cylinders that potentially outperform those made by conventional forging, both in terms of material efficiency and mechanical properties. Such findings are significant as they point towards more sustainable and cost-effective manufacturing methods that do not sacrifice quality.
Abstract
Wire arc additive manufacturing (WAAM) is an advanced additive manufacturing (AM) technology that offers low cost and high deposition rates, making it suitable for building large metal parts for structural engineering applications. However, various welding procedures result in differing heat inputs and repetitive heating treatments throughout the deposition process, which can affect the microstructural and mechanical characteristics of the parts. In the current study, cylindrical parts made of 304L austenitic stainless steel (ASS) were manufactured using the WAAM technique, employing both gas metal arc welding (GMAW) and cold metal transfer (CMT) processes. This study explores the correlation between WAAM techniques and their effects on the bead geometry, microstructure and mechanical properties. The paper presents detailed analyses of the microstructure using techniques such as optical microscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). The research findings suggest that the choice of arc welding process significantly affects the grain size, phase distribution, and defect formation within the 304L stainless steel, thereby influencing the mechanical properties and overall performance of the manufactured components. The WAAM-processed 304L ASS cylinders showed better performance compared to those manufactured using traditional industrial forging standards, indicating that WAAM-processed 304L ASS cylinders are suitable for industrial applications. This comprehensive evaluation provides insights into optimising welding processes for enhanced quality and performance of stainless steel cylindrical parts.
Highlights of the research
- Controlling heterogeneous microstructures in WAAM-processed 304L stainless steel is challenging.
- GMAW vs. CMT impacts on 304L ASS microstructure analysed.
- The upward growth of coarse austenite/ferrite morphologies is controlled by the wire retraction mechanism.
- CMT produced finer dendrites and more ferrite morphologies.
- WAAM 304L ASS components outperformed the wrought 304L ASS and forged 304L ASS.
Practical implementation/Social implications of the research
The practical implementation of Wire Arc Additive Manufacturing (WAAM) for 304L austenitic stainless steel could revolutionise multiple industries, including aerospace, automotive, medical devices, maritime, and energy, by allowing the production of complex, custom, and durable components with greater efficiency and reduced material waste. This shift not only promises economic benefits like cost reduction and job creation in advanced manufacturing sectors but also carries significant environmental advantages by minimising waste and the carbon footprint associated with traditional manufacturing processes. Furthermore, the technology enhances supply chain resilience by enabling local, on-demand production, which could be crucial during global disruptions. Socially, WAAM could increase access to customised medical aids in low-income regions, fostering greater equality. The adoption of WAAM thus holds the potential to impact manufacturing practices profoundly, driving innovation, sustainability, and inclusivity across various sectors.

This research will aim to leverage the unique properties of each metal to create components with tailored functional performance for demanding applications. Key challenges will include optimising material interfaces, controlling deposition processes, and ensuring structural integrity.
