摘要：随着科学技术的发展，尤其是单片机技术和半导体技术的高速发展，利用单片机控制仪器的研究及应用越来越受到重视。目前，盆栽植物越来越受到城市居民的喜爱，但是往往存在着人工给盆栽植物浇水带来的局限性，为了克服传统测量方法测量不精确，而且测量的范围也比较小，并且十分的不方便，已经不能满足现代高速发展科学的需要，本文所介绍的盆栽植物生长过程土壤水分测控系统基于单片机控制，再配合土壤湿度检测电路设备探测盆栽植物所在的土壤环境，电磁阀门和可以根据不同植物进行多种灌溉方式的灌头，既克服了传统的人工浇水的不定时性和不准确性，又避免了以往水分控制系统的不准确性而造成的过涝等，因此的盆栽植物土壤水分测控系统以降低设备投入，同时也不用自己去专门维护、检修，是比较理想的选择。本毕业论文系统以AT89S51单片机为控制器，C语言编程，采用直观的LCD1602液晶屏显示，采用土壤湿度监测模块，单片机控制模块，电磁阀门灌水模块所构成。此盆花自动浇水系统具有读取方便、显示直观、功能多样、电路简洁、成本低廉等诸多优点，具有广阔的市场前景。

Abstract：With the development of science and technology, especially the technology of single chip and semiconductor technology high speed development, the use of single-chip microcomputer to control equipment research and application has been paid more and more attention. At present, potted plants by more and more city dwellers, but often there is a manual to potted plant watering some limitations, in order to overcome the traditional method is not accurate, and the measuring range is relatively small, and very convenient, has been unable to meet the rapid development of modern science, this article introduced the pot plant growth process of soil moisture measurement and control system based on single chip microcomputer control, coupled with the soil moisture detection circuit for detecting a potted plant equipment where the soil environment, electromagnetic valve and can be different according to the plant for a variety of irrigation heads, which overcomes the shortcomings of the traditional artificial watering of timing and inaccuracy, and avoids the moisture control system the inaccuracy caused by the flood, so the potted plant soil moisture measurement and control system in order to reduce the equipment investment, but also have their own special maintenance, repair, and is an ideal choice. The graduation thesis system to AT89S51 for controller, the C programming language, by using object LCD1602 screen, the soil moisture monitoring module, single-chip microcomputer control module, electromagnetic valve irrigation module place is formed . This potted plant automatic watering system is convenient, intuitive display, multiple functions, simple circuit, low cost and other advantages, has broad market prospects.
