Abstract

RIVER WATER QUALITY MONITORING EQUIPMENT AND CONTROL BASED ON WIRELESS SENSOR NETWORKS

Afolabi M. O., Oluborode G. B.* and Agbi J. I.

ABSTRACT

We have designed and presented a wireless sensor network monitoring and control equipment for Rivers. The developed monitoring equipment consisted of five units: data monitoring nodes, data base station, remote monitoring center, power supply unit and display unit. The power supply unit consisted of solar cells and lithium cells. The dissolved oxygen sensor, pH electrode, temperature sensor, turbidity sensor, conductivity sensor and depth sensor present in data monitoring mode were used to measure and monitor the water quality parameters of River Niger in Nigeria. A microcontroller chip was used for processing data collected; GPRS modules were also used for data transmission to the remote monitoring center. Various parameters of the River such as dissolved oxygen, temperature, electrical conductivity, pH, turbidity and water level were detected and control in real time. The water quality parameters were sent through short messages from the base station via the Global System for Mobile (GSM) module for notification. The water pH was found to range from 7.1 to 7.43 with temperature range from 27.3°C to 29.8°C. Other physicochemical parameters values monitored did not exceed the recommended values for surface water quality. Experimental results obtained using this locally developed monitoring equipment showed that the equipment is more reliable for large scale deployments on water quality in Rivers.
