Polluted water monitoring based on wireless sensor

Polluted water monitoring system should have the characteristics of transferring data timely and validly, arranging monitoring points flexibly, and so on. Monitoring system based on wireless sensor can meet this requirement well. It can easily form the network, collect data and transfer to the host computer using wireless sensor network. The host computer displays the data directly in the format of value and curve, stores data in database, queries the history data, and provides alarm signal when polluted level exceeds the standard value. This paper has designed terminal node, router node and coordinator node based on ZigBee technology. Through these three kinds of node, polluted water monitoring system can work well. The user interface is programmed with configuration software MCGS.
