This paper design a daejeon agricultural environment monitoring network based on the ZigBee protocol , effec-tively solve the daejeon environmental monitoring difficulties and shortcomings like equipment wiring complexity , high cost, and smaller range communications , improving the agricultural data collection precision and access to real -time. The system uses embedded technology to achieve lower machine data acquisition , ZigBee communication protocol to a-chieve node data aggregation and send , the VPN set to achieve the remote maintenance system , HTTP technology to en-sure the integrity of the data received , the overall system constitute from three modules :ARM+LINUX modules , ZigBee wireless sensor network , the host computer information management system , ARM +LINUX embedded modules for data acquisition , and then by the ZigBee wireless sensor network for data transmission , data released by the information man-agement system .This paper we use the Anhui province Suzhou city Lingbi county as the study area .,to monitor the air temperature , air humidity , soil temperature , soil moisture , total solar radiation , wind speed , wind direction , daily rain-fall, select 26 samples to compare with the measured value of the actual field , the air temperature accuracy is 83.67%, the air humidity accuracy is 87 .11%, the soil temperature accuracy is 85 .29%, the soil moisture accuracy is 81 .09%, the total solar radiation accuracy is 88 .17%, the daily rainfall accuracy is 81 .87%, the overall error is 15 .46%.The results show that the system’s data transmission is correct, reliable, at the same time has a good real-time, accuracy, can be promotional applications .
