Traditional aquaculture methods mainly rely on the experience and technology of farmers themselves,which lacks reliable data support,so it is difficult to accurately understand the breeding environment.It can improve the intelligent level of aquaculture by integrating traditional aquaculture technology with modern technology and Internet technology.With STM32 as the core control unit,combined with the FreeRTOS system,the efficient operation of a multi-threaded operation control system is achieved.By deploying multiple sensors,intelligent perception of the envi-ronment can be achieved,which can timely response to environmental changes.And through the control circuit,the water pump,motor and other devices are automatically controlled to adjust the environmental factors inside the pond,and ensure that the environmental parameters meet the preset parameter requirements.At the same time,wireless net-work technology is used to upload monitoring data to the cloud in real time,which is convenient for users to monitor the environmental parameters in the pond at any time through mobile phone APP.In addition,the system can also reg-ularly feed and regularly supply oxygen to improve the efficiency of breeding according to the growth needs of fish.The implementation of this project will help improve the efficiency and yield of aquaculture,reduce breeding costs,and provide strong support for the sustainable development of aquaculture.
