A visual sensing network system has been developed to enable real-time, low-cost, wide-area monitoring of water conditions of rivers and lakes. It is composed of newly developed water-quality sensor modules that measure seven items (pH, amount of dissolved oxygen, etc.), television cameras, and a central workstation. The central workstation controls the other components and obtains the measured data and images through a network. A one-year field test showed the effectiveness and reliability of the system. This paper focuses on the system design and field test results.
