Water Quality Monitoring System based on WSN

Abstract: With the growth of economy in recent years, the water quality monitoring becomes a critical issue about water pollution. Water Quality Monitoring has a big influence on the aquaculture management, waste water treatment, drinking water and some other applications. There is a trend to build a wireless sensor network system for water quality monitoring. This system detects pH, conductivity, dissolved oxygen, turbidity, temperature, ORP (Oxidation-Reduction Potential), BOD (Biochemical Oxygen Demand), Flow and etc. Some important electrochemical parameters of water quality should also be detected, like Ca2+, Mg2+, Cl2, Cl-, NO3-, NH3+, CO2/CO32-, F-, BF4-, K+, Na+. The water quality monitoring system should guarantee the accuracy, security and reliability. In this paper, I research an integrated system model for water quality monitoring system which is based on chlorine analyzer, turbidity meter, pH meter, conductivity meter, dissolved oxygen meter and so on. I analyze the water quality monitoring program according to different physical environment.
