Announcing the Winner of Prove It: Arduino UNO Q Community Challenge
Smart Water Guardian AI Sets a New Standard for Edge Intelligence
The winner of Prove It: The Arduino UNO Q Community Challenge is Biaou David Barthélémy Kochoni, recognised for the project Smart Water Guardian AI.
The competition attracted a wide range of high-quality submissions, with participants exploring innovative applications of the Arduino UNO Q across real-world challenges. Selecting a winner proved difficult, reflecting both the creativity and technical capability demonstrated across the community.
Smart Water Guardian AI ultimately stood out for its clear purpose and thoughtful execution. Judges highlighted its relevance and technical approach, with one noting it was “a great proposal for a concept,” while another praised its “good use of AI” and “extensive support material.” The strength of the presentation and the clarity of the idea helped set it apart in a highly competitive field.

Tackling a Real-World Problem: Safe Water
Access to safe water remains one of the most pressing global challenges. Contamination rarely occurs as a single event. Instead, it develops gradually, often going unnoticed until conditions become unsafe.
The concept behind Smart Water Guardian AI is built on recognising this pattern. Rather than simply reacting to predefined thresholds, the system is designed to identify early shifts in water quality before they escalate.
This has relevance at multiple scales. One judge observed that it addresses “a use case that everyone who has a water system will face.” While the broader implications include community water systems and agriculture, the underlying problem is familiar and immediate, making the solution both practical and accessible.
Detecting Water Quality Issues Before They Escalate
Traditional monitoring systems tend to treat water quality indicators independently. They trigger alerts once specific limits are crossed, which often means the issue has already progressed.
Smart Water Guardian AI takes a different approach. It looks at water quality as a combined profile across time, analysing how multiple factors behave together. Using a K-means anomaly detection model, trained on normal conditions, it can recognise when this profile begins to shift.
This allows the system to flag potential contamination earlier, even when individual readings remain within accepted ranges. The result is a move towards predictive monitoring, where users can act before a situation becomes critical.
Judges recognised the significance of this approach, noting that “the problem is very real and would be a meaningful use of AI.”
Designed Around the Arduino UNO Q
A key element of the project is how effectively it uses the Arduino UNO Q.
The system divides responsibilities between its two processing environments. The microcontroller handles real-time sensing and control, while the Linux-based processor manages data processing and AI inference. Communication between the two is handled through the platform’s Bridge functionality, allowing them to work together as a cohesive system.
This architecture enables local processing without relying on cloud infrastructure. It also allows the project to maintain both responsiveness and computational flexibility, which is essential for combining sensor data with real-time analysis.
A Practical Concept With Future Potential
Smart Water Guardian AI is best understood as a proof of concept that demonstrates what can be achieved with accessible hardware and thoughtful design.
The project already brings together several key elements, including multi-sensor input, time-series analysis, and on-device AI. It also integrates alerting and visualisation, showing how a complete monitoring workflow could operate in practice.
At the same time, there is clear opportunity for further development. Expanding the training data, refining the model, and testing in different environments would all contribute to making the system more robust. There is also strong potential to scale the concept through networks of distributed monitoring nodes.
What stands out is not only the current implementation, but the direction it points towards.
Why It Won
Smart Water Guardian AI demonstrated a strong balance between technical ambition and real-world relevance.
Judges responded to:
- A clearly defined and meaningful problem
- A well-considered use of AI that adds practical value
- A strong supporting narrative, backed up with detailed material
It's a project that shows how emerging technologies, such as the UNO Q, can be applied in a grounded and accessible way, without losing sight of the real-world context.
About the Winner
Biaou David Barthélémy Kochoni is currently studying at Jean Monnet University in France, where he is pursuing a Master’s degree in Signal Processing and Instrumentation Engineering.
With a strong interest in both electronics and artificial intelligence, his work reflects a clear focus on combining these disciplines in practical, real-world applications. He is particularly motivated to continue developing his expertise in embedded systems and edge AI, areas that are central to both this project and the broader future of intelligent devices.
Looking Ahead
Smart Water Guardian AI highlights the growing role of edge intelligence in environmental monitoring. By combining low-cost components with local processing, it offers a glimpse of how more responsive and decentralised systems could be developed in future.
A massive congratulations to Biaou David Barthélémy Kochoni on a well-deserved win. The quality of submissions across this year’s challenge reflects a community that is both technically capable and motivated to tackle meaningful problems.
It will be interesting to see how ideas like this continue to evolve beyond the competition... I personally can't wait to see what the community comes up with next!
