Abstract: The soil moisture monitoring system was developed for the sake of knowing the soil moisture in Jilin Region, Jilin province. The system was consisted of a sub-center, five information stations located in five main drought-resistant counties, and thirteen soil moisture monitoring stations distributed in the Region. Soil moisture monitoring stations acquire the raw data of soil moisture on time everyday, and transmit the data to the information stations, and then information stations exact the soil moisture from the raw data and transmit it to sub-center, the sub-center will make a drought prediction or alarm of the region by analyzing the soil moisture and make a drought-resistant blue print. The reliability and practicability of the system has been validated by running continuously over two years.
