摘 要：Soil humidity is considered as one of important soil parameters and is already used widely in agriculture information system.The measurement of the soil humidity,characterized by accuracy and continuity,can help build useful information systems for modem agriculture.Remote detection of soil humidity can be achieved easily by using wireless sensors network (WSN).In this paper,a way to build an automatic irrigating system taking advantage of humidity measurements,which is obtained based on Wireless Sensor Network,is proposed.That how the humidity is detected and how the WSN is constructed is discussed.Furthermore,the connection of hardware devices and theprograms of software is described.
