Water pollution is one of the biggest fears for the green globalization. In order to ensure the safe supply of the drinking water the quality needs to be monitor in real time. In this paper we present a design and development of a low cost system for real time monitoring of the water quality. The system consist of several sensors is used to measuring physical and chemical parameters of the water. The parameters such as temperature, DO, Turbidity, conductivity and PH of the water can be measured. The measured values from the sensors can be processed by the core controller. Finally, the sensor data can be processed and send to the system.
