Abstract: Soil moisture information is an important scientific basis for precision fertilization and irrigation in the modern agriculture. In order to acquire this information rapidly and precisely, a specific design of the remote monitoring system for soil moisture based on 3S (GPS/GIS/GPRS) technology alliance was proposed. This system consisted of the monitoring network nodes and a remote system server. By means of the ZigBee-based wireless sensor networks within a small scale, the GSM/GPRS/GPS networks within a large scale and their mutual communication with the worldwide internet, this system implemented advanced functions such as automatic data acquisition, wireless transmission and nodes orientation. Besides, long-duration solar-powered wireless sensor nodes and sink nodes were designed. The information management software running on the system server was developed for setting remote parameters and monitoring real-time data. This system may play an effective role in soil moisture information monitoring and decision-making analysis.
