A Wireless Ecological Aquaculture Water Quality Monitoring System Based on LoRa Technology

For the development of the direction and scale of aquaculture, the requirements for aquaculture technology and the environment are constantly increasing. In the process of aquaculture, the high requirements of parameters such as dissolved oxygen content and PH value of water quality make water quality monitoring an indispensable link in aquaculture. However, at present, most of the traditional water quality monitoring systems have exposed many disadvantages such as cable laying, inconvenient maintenance and maintenance, and lack of intelligent management and control behavior. At the same time, consider the characteristics of the long-node propagation distance of large waters such as Dongting Lake, this paper proposes a LPWAN water quality monitoring system based on LoRa technology with long single-hop transmission distance. The monitoring system fully utilizes the characteristics of long life, low power consumption, simple network protocol and topology, and low deployment and maintenance cost of the LoRa technology node. Keywords—wireless sensor networks; water monitoring; LoRa; Dongting Lake
