Abstract: In this paper, a technical scheme of a WEB based monitoring and publishing system for greenhouse environment data was presented firstly, and the detailed description of the system was given to introduce the implementation of the hardware and software afterward. This remote supervisory system was established based on the Browser-Server(B/S) Mode Developed with Microsoft VB.NET and ASP.NET technical criterion. The hardware was composed of 3 parts: a PC computer that can access to internet, a RS-485 bus cable as a middle bridge connecting both the PC and digital sensors, all of which formed a field monitoring system for greenhouse environment information. The result showed not only the real-time greenhouse environment data could be acquired and browsed in a remote site, but system parameters could be edited and set up through accessing to the internet. In addition, this system was not only available to realize data acquisition and management for a greenhouse, but could be easily adopted to other agricultural field as also from other remote places.
