Research on the Sensor Node of the Unattended System for Remote Monitoring of the River and Lake

In order to monitor the water quality of rivers and lakes in real time in indoors, and protect the green hills and blue waters, a remote monitoring system of unattended surface water quality based on WSN (wireless sensor network) is designed and studied. The structure of the on-line monitoring system of water quality is studied, and the network and communication of the monitoring network are realized. Designs the pH monitoring sensor node, the intelligent wireless sensor network and the real-time information processing system are designed, and the information acquisition, processing, production, broadcasting and other functions of the whole system are finally completed. The experimental results show that the data transmitted by the method is accurate and reliable, can monitor the water quality of the river and lake basin in real time, and provide reference basis for the decision-making department, and provide real-time information for the good condition of the surface water quality.
