Sensor-Based Water Quality Parameter Measurements across Three Pilot Sites in Coimbra

Three independent raw datasets of sensor-based water quality measurements, each corresponding to a distinct pilot site in Coimbra. Each dataset contains time-resolved in-situ measurements of physical parameters—temperature, pH, dissolved oxygen, electrical conductivity, and oxidation–reduction potential—together with multi-channel spectroscopic wavelength responses. The datasets capture site-specific water quality dynamics under real operational conditions and provide a basis for comparative analysis, and data processing for advanced modeling.
