基于单片机控制的按需按时智能自动浇水系统

On-demand Intelligent Automatic Watering System Based on Microcomputer Control

本文设计了一种基于单片机控制的自动浇水系统,系统以单片机AT89C51为控制芯片,利用土壤湿度传感器来检测植物土壤的相对湿度,然后通过AT89C51单片机进行信息处理,输出控制信号控制水阀的开合,完成按需按量自动浇花的工作,当土壤湿度达到设定值时停止浇水,该设计含有自动报警系统,启动浇花之前先有蜂鸣器报警,所有控制都利用C语言向单片机写程序,系统软件的开发全部采用KeiluVision3进行,并选用1602液晶显示模块直观地体现系统的工作状况。本智能浇水系统实现了在无人状态下自动按需按时浇水,可以使土壤湿度达到植物生长所需的最佳值,极大地方便了人们的生活。

This paper designed an automatic watering system based on single-chip microcomputer control. The system uses AT89C51 as the control chip, and uses soil moisture sensor to detect the relative humidity of the plant soil. Then it processes the information through the AT89C51 microcontroller and outputs the control signal to control the opening of the water valve. Together, complete the automatic watering work according to the required amount, stop the watering when the soil moisture reaches the set value, the design contains an automatic alarm system, buzzer alarm before the start of watering, all the control use C language. The programming of the MCU and the development of the system software all use KeiluVision3, and the 1602 liquid crystal display module is used to intuitively reflect the working status of the system. The intelligent watering system realizes automatic watering on time according to need in an unmanned state, which can make the soil moisture reach the optimum value for plant growth and greatly facilitate the life of people.
