Abstract
Due to the nowadays demanding for the environmental concerns and the growing importance of the pollution reduction for a sustained development, the water quality monitoring it’s very important and useful to study the physical and chemical characteristics of all kind of water and essential to understand the needs to protect and recover the quality of one element which is vital to all of us and also all the beings who surround us. The present work has the target to develop a low cost virtual instrument for water quality parameters measurement. The developed system allows to measure three of the most important physical variables in water quality monitoring that are: electrical conductivity, temperature and turbidity. An important characteristic is the flexibility to add also other measurement channel without significant change of the system hardware component. Making measurements for several hours in the remote locations it is possible due to system autonomy provided by appropriate battery supply selection. The designed and implemented virtual instrument is characterized by accuracy that satisfied the application requirements of water quality assessment in revers and estuaries.
