Quality assessment of system for automated multi-node environmental water parameter monitoring

This paper presents a system for automated multi-node environmental water parameter monitoring and makes an assessment of its measurement quality. Using this system, by constant monitoring of water quality in wetlands and surrounding areas, and analysis of long-term measured data can yield key and useful information for environmental protection and biodiversity actions and plans. The system is built as a network of independent measurement nodes, each equipped with probes for measurement several key physicochemical parameters. Acquired data are sent using commercially available communication networks to a central data-center for further processing, analysis and presentation. The system was tested in laboratory condition. Measurement results of water samples taken from wetlands are compared to results obtained by physicochemical laboratory analysis, resulting in the quality assessment of the designed system.
