一种智能土壤湿度测量和控制系统设计(论文12600字)
摘要:为了降低对作物生长环境的人工管理成本,实现对土壤墒情的自动控制,让人们从繁琐的灌溉工作中解放出来,提出了基于STC89C52单片机和YL-69型土壤湿度传感器,设计了一种智能测量和控制土壤湿度的系统。整套系统由六大部分组成:单片机主控模块、湿度测量模块、显示模块、按键模块、报警模块和驱动模块,用于实时监控土壤墒情,可灵活调节阈值,以适应不同作物对土壤墒情的要求,并采取相应的浇灌或通风措施。该系统节约资源,有效提高了农业智能化程度。

An intelligent measurement and control system for soil moisture
Abstract:In order to reduce the cost of artificial management of crop growth environment, to realize the automatic control of soil moisture,and to free people from the tedious watering work, based on STC89C52 singlechip and YL-69 type soil moisture sensor, an intelligent system of soil moisture measurement and automatic control is designed. The whole system is composed of six parts: single chip microcomputer main control module, humidity measurement module, display module, keystroke module, alarm module and driving module. It can be used to monitor the soil moisture in real time and adjust the threshold flexibly to meet the requirements of different crops to soil moisture, and take the measures of irrigation and ventilation. The system saves resources and effectively improves the level of agricultural intelligentization.
Key words:Soil moisture monitoring;single chip microcomputer;intelligence
