A Review On Real Time Embedded System For Asscessment Of Potable Water Quality

Abstract

This paper presents review on design and development of proposed embedded system for real time monitoring of potable water quality at user sites. The intended system may consist of several optical and electrochemicalsensors like turbidity, pH, electrical conductivity, temperature etc. and special attention has given on making system light weight, reliable and durable. This kind of system is required for collecting the large spatiotemporally rich data to local government, water development board and water companies. Extensive literature and market research has performed to find water quality parameter and its respective sensor. Based on selected parameters wireless sensor node is developed along with several microsystem required for analog signal conditioning, processing and remote representation of data. Finally various event detection algorithmsfor fusion of differentdata collected by sensors in real time are studied so as to find outthe anomalies and different contaminant present in drinking.Also the hazardous effect of these parameters on human health is discussed when specific parameter related to quality of water crosses their prescribed limit.
