Aiming at the problems of high cost, low efficiency, lack of systematic management and intelligent monitoring, a set of remote water quality monitoring system based on Lora technology and 4G Network is designed. The system uses solar battery as power supply, and F8L10T_LoRa as acquisition terminal module. The data of DO (dissolved oxygen), PH and temperature collected by the sensors are uploaded to F8926L_Router gateway. The gateway uses 4G Network to communicate with upper computer software. And the Kingview software is adopted to display and store the data in real time. The results show that the system can accurately obtain the data of each pond in real time, and the packet loss rate is less than 2% in the range of 5 km during the three-month test.
