In order to solve the problem of lack of monitoring tools in current aquaculture, a scheme for aquaculture monitoring system is proposed. The system based on embedded technology, GSM/GPRS communication technology and RF wireless transmission technology is mainly realizes the real-time monitoring of aquaculture environmental indicators, such as temperature, dissolved oxygen content, PH value, etc. The system has the advantages of simple structure, fast data transmission speed, easy expansion function, etc. The aquaculture monitoring system is suitable for many fields, such as industrial aquaculture, water environment, intelligent greenhouse and so on.
