Real-time monitoring of oxygen content in fish ponds is of great significance for the intelligent management of fish ponds. This paper proposes a method to realize multi-point real-time monitoring of Dissolved Oxygen content in fish ponds by using Internet of Things technology. The system is mainly composed of three parts: measurement circuit, control circuit and data processing module. The measuring circuit completes the real-time measurement of the Dissolved Oxygen content of the fish pond; the control circuit can complete the oxygen-filling operation according to the set value of the oxygen content; the data processing module can record the historical data in real time and complete the cloud processing of the data and related background operations. After testing, the system can effectively realize real-time monitoring of Dissolved Oxygen content in multi-point fish ponds and control the cost of aerators, thereby effectively reducing losses and increasing production.
