针对目前我国农业灌溉用水量大、水资源利用效率低的问题，基于ZigBee 无线通信技术设计了田间灌溉自动测控系统。通过湿度传感器 HM 1500测量土壤的水分，经下位机单片机系统采集，并通过 ZigBee 无线数传模块发送土壤水分含量数据至上位机；上位机能够实时监测现场数据，并通过与设定的土壤水分下限值进行比较，若达到灌溉要求则经 ZigBee 发送命令至下位机，启动水泵灌溉。设计的测控系统成本低、性能优，为节水灌溉系统的设计提供了借鉴。

According to the status of agriculture irrigation with much water consumption and low efficiency , the automatic observe and control system is designed based on ZigBee wireless technology .The lower monitor gets the soil moisture con-tent by HM1500 and sends the data to upper monitor through ZigBee module .The upper monitor shows the information and compares the data with lower limit which is set , the start-up order is sent to the lower monitor with ZigBee transmis-sion .The system has the character of low cost and good nature , and also provides a reference for water saving irrigation system design .
