- Overview of HydroSense
- HydroSense is an innovative Internet of Things (IoT) solution developed for the continuous and real-time monitoring of lake water quality. This system employs a buoy equipped with various sensors to measure multiple water parameters, offering a more efficient and timely assessment compared to traditional manual sampling methods.
- Background and Purpose
- Traditional methods of analyzing lake water quality involve manual sampling, typically performed only a few times per year. This sporadic testing results in a lack of real-time data, making it difficult to monitor ongoing pollution and environmental changes. The European guideline EG/2000/60 highlights the necessity for automated monitoring solutions, prompting the development of HydroSense to address this need.
- Technical Details
- Hardware Components:
- Sensors: The buoy is equipped with four sensors:
- One single sensor
- Three sensors integrated into a multiparameter sonde
- Power Supply: The system is powered by solar panels, ensuring a sustainable and continuous power source for the sensors and other components.
- Software and Connectivity:
- Dashboard: Data collected by the sensors is transmitted to the IoT Future Lab Dashboard, where it is visualized and analyzed.
- Connectivity: Uses Narrowband IoT (NB-IoT) for reliable and efficient data transmission from the buoy to the dashboard.
- Solution Description
- HydroSense monitors the following water parameters:
- Temperature
- pH Level
- Electrical Conductivity
- Redox Potential
- Dissolved Oxygen
- Turbidity
- The buoy’s design, including its case and swim body, is 3D printed to ensure cost-effective production and deployment. The collected data is sent over NB-IoT and displayed on a dashboard, allowing for real-time monitoring and analysis of lake water quality.
- Application Opportunities
- The HydroSense solution can be deployed in any lake, making it highly versatile. Potential applications include:
- Municipal Use: Cities and communities can use HydroSense to monitor local water bodies.
- Environmental Restoration: Companies involved in environmental restoration projects can leverage this technology to assess and improve lake conditions.
- Project Timeline
- The development and implementation timeline for HydroSense includes:
- 07 June 2022: Project initiation
- 20 July 2022: Arrival of sensors
- 05 August 2022: Completion of swim body and case
- 05 September 2022: Project completion
- 08 September 2022: Implementation with Landesanstalt für Umwelt Baden-Württemberg (LUBW) at Bodensee
- Showcase Features
- The HydroSense showcase is a scaled-down, interactive version designed for demonstrations:
- Measured Parameters: The showcase focuses on two key parameters: oxygen and temperature.
- Design: It features a 74-liter tank with synthetic plants, stones, and sand to simulate a natural lake environment. Sensors float in the water and send real-time data via 5G to a dashboard.
- Interactivity: Users can alter water conditions using two buttons:
- One button increases oxygen levels.
- Another button raises the water temperature.
- These changes are accompanied by bubbles and lights for an engaging and educational user experience.
- Future Development and Communication
- HydroSense's showcase is set for further testing and lab establishment by March 2023. Communication strategies include updates through Vodafone's external and internal channels, such as the newsroom and social media platforms, ensuring widespread awareness and engagement with the project.
- Conclusion
- HydroSense represents a significant advancement in automated environmental monitoring, providing real-time data and analysis to help manage and protect lake ecosystems. Its innovative design and technology make it a valuable tool for municipalities, environmental organizations, and restoration projects.
