Design and Implementation of a Low-Cost Real-Time In-Situ Drinking Water Quality Monitoring System Using Arduino

Water can be considered as an important limited and critical resource over the world. This significant resource is essential for agriculture, industry and for creature's existence on earth including human beings. Water quality monitoring is becoming increasingly important due to the rapid presence of several different sources of pollutants and contamination. This paper presents an approach to build an effective low-cost, real- time and in-situ water quality monitoring system using arduino microcontroller. The proposed approach aims to design a Iow- cost system for real-time and on-site water quality monitoring using low-cost and accurate commercial off-the-shelf sensors and arduino programming language. The main aim of this work is to design a monitoring system that can overcome some of the limitations of traditional water quality monitoring systems in terms of high-cost and non real-time operation. In addition, the performance of the proposed system through conducting several experimental tests is evaluated. Experimental results show that the proposed system is capable of accurately monitoring the water quality continuously and in a timely manner with low cost.
