The idea of 'Wireless Sensor Network' (WSN) is the basic building block of a water quality monitoring using Wireless Sensor Network (WSN) technology. To monitor water quality over different sites as a real-time application, an excellent system architecture constituted by distributing sensor nodes and a base station is suggested. The nodes and base station are connected using WSN technology like Zigbee. Base stations are connected via Ethernet. Design and implementation of a prototype model using WSN technology are the challenging work.
