Periodic Monitoring of Rivers Using Portable Sensor System

Rivers are the lifeline of human civilization from ancient times and almost all the human settlements had evolved around it. In this present era, human population has grown at a rapid pace and the anthropogenic activities have grown along with it. Pollution levels of rivers are increasing day by day due to increase in anthropogenic activities, as huge amount of waste gets disposed into it. Several kinds of waste including domestic and industrial waste have been a major source of pollution for the rivers. These pollutants have severely affected the aquatic ecosystem. To keep a check with the increasing pollution levels in the rivers, periodic monitoring of river water quality is essential. In this paper, we present a low cost sensor system model which comprises Arduino, designed and developed for the periodic monitoring of river Ganga. Water quality parameters like turbidity, Dissolved Oxygen (DO), pH and temperature are measured on periodic basis. Recorded sensor data can be transferred to the computer system and still processed further.
