I am a 17-year-old high school student from Germany, and I am interested in environmental protection and innovative technology. Together with a partner, I developed WarnMe, a simple, low-cost, and user-friendly flood warning system. It is designed to measure water levels and flow speeds in real time and to warn people early through our own app. I enjoy working on practical solutions to real-world problems and environmental issues. Being part of the Stockholm Junior Water Prize is a great opportunity for me to share our idea and connect with others.
Tell us what the water concern in your country is!One key water issue in Germany is the increasing frequency of local heavy rainfall events due to climate change, leading to more flash floods and growing regional water imbalances.
This is what I think is one of the solutions for a sustainable future:A sustainable future can be achieved by protecting and managing water resources responsibly through efficient use, reducing pollution and contamination, and restoring ecosystems. This approach ensures clean water for everyone, supports biodiversity, and builds resilience to adapt to future climate challenges.
WarnMe - Early flood warnings for everybody!
In view of the increasing number of heavy rainfall events, we have developed WarnMe – a flood warning system. It records water levels in real time using infrared and ultrasound sensors and measures flow velocity via radar. The data is sent to our server via LoRaWAN, where it is analyzed using intelligent algorithms. A user-friendly app ensures that users are immediately informed of potential hazards. Simple installation instructions enable independent setup without professional assistance, creating a decentralized, cost-effective, and scalable system. In summer 2024, WarnMe successfully detected an imminent flood event and contributed to public safety by issuing timely warnings to the affected population.
