Wireless remote central monitoring system for freshwater lakes

초록

The management of water resources is closely related to human life. Thus the operation of various devices for water circulation, algae control and water quality control of scattered freshwater lakes is paramount. In this paper, the author designed and implemented a system which monitors water quality in real time. The subjects for monitoring include amount of sunlight collected from various types of photovoltaic inverters, power consumption and data from water quality analysis sensors, e.g. temperature, hydrogen-iron concentration (pH), amount of dissolved oxygen (DO), electrical conductivity (EC), chlorophyll-a (Chl-a), and turbidity. These were accumulated in a BD server on a real-time basis. By using this data, the author developed a system which facilitates real-time integrative monitoring and transmits an SMS alert in the event of an emergency. The suggested system is able to reduce time and manpower because there is no need to visit sites to measure the water quality, thereby increasing efficiency of water quality management and preventing disasters through real-time monitoring of water quality and swift reaction. © 2015 SERSC.
