In order to heighten transmission distance and continuous monitoring, a remote collection and monitoring system of soil moisture content information was developed. Its structure and principle were described in detail, and the software and hardware design were given. The system can be charged by solar energy. Wireless transmission and satellite location of sample stations was realized by GSM net and GPS system. The large area real-time soil moisture content state was monitored and the spatial distribution map of soil moisture was drawn by a GIS software. The application results show that the proposed system is efficient. The established remote monitoring system provides reliable and foundation for fighting for drought.
