Low-cost non-contact multispectral sensor for urban water quality monitoring 1: School of Civil and Environmental Engineering, Queensland University of Technology, Queensland, 4000, Australia; 2: Swiss Federal Institute of Aquatic Science & Technology (Eawag), Überlandstrasse 133, 8600 Dübendorf, Switzerland; 3: School of Environmental Sciences, Ontario Agricultural College, University of Guelph, Canada The accelerating pace of urbanization has led to significant accumulation of pollutions in receiving water bodies through stormwater runoff, threatening both aquatic ecosystems and human health. Capturing pollution dynamics requires effective monitoring systems to provide high-frequency measurements while maintain cost-effective for widespread deployment. This study aims at testing a low-cost, non-contact proximal sensing system for urban water quality monitoring. A low-cost (<AUD120) multispectral sensor has been developed through casing and electrical design and its performance has been assessed in the laboratory using real-world samples from four sites in Australia. Both SLR and PLS model can achieve good predictive performance for turbidity (R2>0.93). This result approves the feasibility for turbidity measurement of various water sources. The outcome of this research aims to provide an innovative and reliable solution for urban water quality monitoring that can be deployed at field continuously with minimal maintenance required, which could help us better understand the temporal and spatial dynamics of water pollution. | |
