Water Quality Parameter Monitoring System in Multi-Region Based on IOT

For multi-region fishery water environment, multi-regional water quality online monitoring system is present in this paper, which is implemented in the Android mobile phone. And through it many of water quality parameters in different water region can be monitored online, such as water level, salinity, pH, flow rate, temperature, dissolved oxygen and so on. All these parameters will be saved in SQLite database in Android mobile memory. Communication parameters and alarm threshold parameters can be saved as ini file in TXT mode. The design adopts the mode of socket network communication based on message notification mechanism. The design has low requirement on the network, and has high cost effectiveness. After experimenting and debugging in Jiangsu province Liyang CHANGDANG lake experiment base, the indicators of the system response is good, easy to use, which provides the guidance of fishery production and increase the income of fishermen?
