Development of a web-based wireless telemonitoring system for agro-environment

Abstract

In order to satisfy the requirements of agro-environmental data acquisition, a project scheme of wireless telemonitoring system was plotted out according to the agricultural characteristics of scattered-sites far from developed community, multiple environmental factors, mutable conditions disturbed by natural disasters, and so forth. Integrated with modern information technology (IT), an environmental data acquisition system, named WITSYMOR V1.0, was developed, which was designed to be compatible with most of common sensors, such as temperature and moisture for air and soil, CO2, air pressure, PAR, total solar radiation, soil pH and EC, etc. The kernel techniques were to realize a seamless connection between wireless mobile network (GPRS/CDMA) and Internet with TCP/IP software design, the data from the remote agricultural sites were real-timely acquired and transmitted to the central database servers, and could be browsed, applied and downloaded by authorized users at anytime and in anywhere. At present, it has been set up in some agricultural stations, horticultural greenhouses, methane-gas pools, as well as in animal shelters. The results show that the system works stably, and it is much adaptive to monitor various agricultural environmental factors in the sites far away. © 2008 International Federation for Information Processing.
