Abstract: In this paper, a real-time online monitoring system for fish ponds was designed based on wireless sensor networks to overcome the disadvantage of the observed of traditional means in fish ponds, such as time-consuming and laborious, step complexity and high cost. The system is integrated sensor modules and communication modules. In the monitoring area of fish ponds ,we could get temperature and dissolved oxygen by wireless sensor nodes, and used zigbee network data to transmit to the terminal control system.The terminal control system made judgments and sent alarm signal,at the same time controlled working condition of the oxygen machine. The system,which has MSP430 and XBEE moudle as the core chips,can real-time online and intelligently monitor parameters in fish ponds, such as temperature,dissolved oxygen and so on. Further that the system can be further expanded to use the GPRS or 3G networks to achieve remote monitoring and control.
