An aquaculture monitoring system based on NB-IoT

In the traditional small-scale pond aquaculture field, the vast majority of individual farmers can only carry out the pond aquaculture based on experience and the breeding environment is hard to be accurately monitored, so the lower cost and high profit are unable to be achieved in this paper, an aquaculture monitoring system based on the narrow-band IoT is designed. The system is composed of acquisition and control module, wireless transmission module and user monitoring module. With the STM32L151RCT6 microcontroller as the core, the acquisition and control module are used to collect water quality parameter information and control the actuator to realize the adjustment of water quality parameters. In addition, after the water quality parameter information is transmitted to the STM32F103C8T6 through ZigBee wireless network, it is displayed on the LCD screen in real time and uploaded to the cloud platform. Users can monitor the aquaculture environment through the Web and mobile phone. The experimental results showed that the designed aquaculture monitoring system can realize the collection, monitoring and control of water quality parameters such as dissolved oxygen, PH and temperature.
