Design of WSN node for water pollution remote monitoring

A water pollution remote monitoring system based on Wireless Sensor Network is proposed for the protecting the ecological environment of water resources. WSN nodes are made from float-type fixed in the monitoring waters. The low power consumption C8051F930 is as the controller, the pH glass composite electrode sensors are used to measure pH, pH sensors collect the signal is processed, converted and disposed according to the potential measuring principle of pH composite electrode. Field data is transmitted and converted by the low power consumption wireless RF transceiver module Si4432, the water pollution of river basin is monitored by remote real-time.
