Intelligent Fishpond Monitoring System Based on STM32 and Zigbsee

摘要

The study is designed to monitor the temperature and dissolved oxygen content in the fishpond, especially to ensure that dissolved oxygen content in the fishpond is enough for aquaculture. This fishpond monitoring system is designed based on stm32 and Zigbee wireless transmission technology. This study uses Zigbee to build up a sensor network to monitor multi fishponds. Data acquisition unit consist of temperature sensor and dissolved oxygen sensor. The sensor data is transfered from the data acquisition unit to the stm32 master controller. These data can be used to generate a control strategy, which can control the oxygen-enriching machine to produce enough oxygen for aquaculture in the most optimized way. The data transformation between master controller and data acquisition is through Zigbee protocol radio communication, which is a reliable means to transfer data. Experiments results show that this fishpond monitoring system can achieve remoting monitoring and control dissolved oxygen content in an effective way. By controlling the dissolved oxygen in the fishpond, the system can increase the production of the aquaculture and decrease the breeding cost.
