Discuss here what was achieved (wrt the initial objectives) and what is missing (wrt the initial objectives) of the project.

Although the prototype demonstrates the core functionality of the TRAQUA concept, several limitations remain. The water quality assessment relies mainly on TDS and temperature measurements. While these parameters provide useful information regarding mineral content and general water conditions, they cannot identify specific contaminants, heavy metals, or chemical pollutants. Thats why, the system should be considered an initial water-quality indicator rather than a complete water-safety solution.

The UV-C disinfection system was designed with multiple safety measures, including a magnetic reed-switch interlock. However, the effectiveness of the sterilization process depends on factors such as exposure time, water clarity, and component positioning. Comprehensive microbiological validation was beyond the scope of this project.

The prototype was developed under strict budget and time constraints, resulting in the use of commercially available development boards and sensor modules. As a result, the system is larger, less energy-efficient, and less integrated than a commercial product would be. Battery life, waterproofing, mechanical durability, and long-term reliability have not yet been fully optimized.

Finally, the project exceeded the initial budget target, demonstrating that further cost optimization would be necessary before mass-market production. Future work should focus on custom electronics, sensor downsizing, extended field testing, certification, and refinement of the user experience to transform the prototype into a commercially viable product.

Future development of the TRAQUA system could follow two main directions. One option is to simplify the design and reduce production costs, enabling affordable product tiers with different levels of smart functionality. Alternatively, the system could be enhanced with premium features such as an integrated display or solar energy harvesting to extend battery life.

On the software side, the mobile application could incorporate gamification and advanced health analytics to provide personalized hydration recommendations. The product range could also expand to include multiple bottle sizes or larger purification units for home use. Regardless of the chosen direction, future work should focus on extensive testing to verify the long-term germicidal effectiveness and self-cleaning performance of the UV-C system under everyday operating conditions. Furthermore, personalized recommendations could be refined through more sophisticated user profiling and health-data analysis, allowing the system to better adapt to individual needs. Such functionality could be particularly beneficial for people with medical conditions where proper hydration plays a critical role, supporting improved daily health management and adherence to recommended fluid intake levels.
