Abstract

A new compact water-quality sensing module and a multimedia sensing network system have been developed to enable real-time, low-cost, wide-area monitoring of water. The sensing module and the system showed the effectiveness of environment monitoring ot water. The sensing module is set directly in the water of rivers and lakes to measure several water qualities and is connected to a central workstation via public telecommunication networks such as ISDN. This enables the sensor data and images of the rivers or lakes to be monitored from personal computer terminals anywhere on the telecommunication networks. A one-year field test showed that the water-quality sensing modules operated successfully without maintenance for about two months and that there was high correlation between the monitored data and the manually measured data.
