摘要
根据农田环境的应用需求,为快速、准确地获取农田中土壤体积含水率和水分变化信息,研究一种基于STC90C51单片机的土壤水分检测系统的硬件结构及功能设计。该系统采用基于FDR(Frequency Domain Reflectometry)的传感器作为土壤温湿度的采集端,可实现对土壤水分含量的自动采集、显示、存储和监测。对于土壤水分的监测试验结果表明,该系统性能稳定,工作可靠,为农田监测、节水灌溉等提供了有效、可靠的监测手段。
According to the application requirements of farmland environment for fast and accurate access to farmland soil volumetric water content and moisture change information,research on soil moisture detection system hardware structure and function design based on STC90C51 single-chip microcomputer,as the acquisition of soil temperature and humidity sensor based on FDR（ Frequency Domain Reflectometry）,which can realize the automatic acquisition of soil moisture content,display,storage,and monitoring. Soil moisture monitoring test results show that the system is stable and reliable and provides effective and reliable means of monitoring to farmland monitoring,water-saving irrigation.
