Design and Development of Real-Time Water Quality Monitoring System

Abstract

For agriculture, business and even human life, fresh water is very much essential. Nearly, 70% of its surface water resources and increasing proportion of its groundwater reserves are contaminated. This has become a serious issue in many countries. Hence, an attempt is made to measure the essential and important parameters of water bodies and to determine the contamination level in water. This paper presents a system that is developed to measure the parameters of water such as turbidity, dissolved solvents, pH and temperature. The contamination level of water has been determined by comparing the obtained parameters with their respective ideal ranges. The water parameters have been considered for the purposes of drinking, vegetation and aquatic life. The developed system is equipped with the suitable sensors to measure water parameters. The sensors are interfaced with Arduino UNO and Raspberry Pi for data processing and transmission. The system is designed to float on the water body there by transmitting the measured data trough Wi-Fi to the remote place. The developed water quality monitoring system requires 17 Watts of on-board power and takes 8sec of time for complete processing of one set of data.
