STM32Based Water Quality Monitoring System For Aquaculture

Aquaculture has been record since ancient times in China. And the scale of aquaculture is growing so fast in recent decades that it has been one of the pillar industry in China’s agricultural production. However, the technology of water environment monitoring develops relatively late in China compared to foreign countries. With the development of aquaculture, the future standard is high survival rate and quality. So the precondition is to keep a stable water environment. Some water quality parameters such as temperature, dissolved oxygen, pH, and so on should be received in time.The application of water monitoring system based on the internet of things can obviously improve the efficiency of aquaculture.On the basis of learning the theories of wireless sensor network and embedded system. An aquaculture quality monitoring system based on STM32is designed, which can not only collect and display the water quality data, but also control the aerator. This system is based on STM32microprocessor and wireless RF chip XBee, consists of three parts:water monitoring end device, display device and software on pc. The end device uses low-power MSP430single-chip computer and takes charge in collecting and sending out water quality parameters by wireless RF chip XBee. Besides, it can control the aerator. The display device put ashore is based on STM32,which takes a translated μCOS-Ⅱ as the operating system and uses μCGUI as the graphic user interface. It can not only display the water quality parameters receive from the end device, but also store and send out it through the GPRS.Compared to traditional methods, this system can conveniently show water quality parameters for many measurement positions. And the products have higher quality. It can realize the function of real-time monitoring and data storage, and the data can be used for further research. Meanwhile, this system can easily be expanded to apply to more complex water monitoring occasion.
