Cost-Effective Real-Time Sensor Technology for Monitoring Algal Blooms
- The Korea Institute of Civil Engineering and Building Technology (KICT) has developed a cost-effective real-time monitoring system for algal blooms using optical sensors and sophisticated algorithms.
- The system's optical sensors are more affordable than traditional methods like satellite imaging, enabling consistent field use in freshwater regions prone to algal outbreaks.
- Dr. Lee Jai-Yeop led the research team at KICT, creating a compact sensor platform that categorizes water surface conditions based on lux, UV, VIS, and IR measurements.
- Using Support Vector Machine (SVM) and logic-based models, the system achieved high accuracy in classification and predicting algal bloom conditions.
- The system also quantifies Chlorophyll-a concentrations with a Multiple Linear Regression (MLR) model, exhibiting low error rates and operational efficiency.
- KICT's monitoring system integrates low-cost IoT sensors and logic-based models, offering a sustainable alternative to complex and expensive monitoring approaches.
- This innovation aims to democratize access to water quality monitoring tools, particularly benefiting resource-limited regions and organizations.
- The system's robustness, interpretability, and real-time capabilities make it ideal for remote environments with limited resources, enhancing ecological monitoring efforts.
- Supported by KEITI and the Korea Ministry of Environment, the KICT study showcases the importance of investing in innovative environmental monitoring technologies.
- The research heralds a new era in cost-effective environmental monitoring, encouraging further advancements to combat harmful algal blooms and protect water bodies.
