Abstract: Aimed at agricultural characteristics, a technical solution was put forward with integrating the embedded system(μC/OS-II Embedded System) and wireless communication techniques for agricultural environment monitoring. ARM CPU was used as the kernel component of the hardware system and the data acquired from the field sensors were transmitted to the remote data server by CDMA/GPRS wireless module. On the server, ASP.NET was used to design dynamic web pages for publishing the information, so that users can easily browse the real time information and download the historical data in any place where the INTERNET can be accessed. The result shows that this system has been improved a lot in its comprehensive functions such as reliability, integrity, stability and expansibility, and so forth, and it was much more suitable for monitoring and managing agricultural environment distributed in remote and dispersive sites.
