基于单片机控制的自动浇灌器设计

Design of Automatic Watering Device Based on Single-chip Microcomputer Control

该文以单片机为控制核心,设计一种能够根据环境光照强度、湿度、温度等参数的变化而自动调节控制,并具有显示功能的智能浇灌器。整个浇灌器由单片机、光强传感器、湿度传感器、温度传感器、前置电路、A/D转换器、电机和水泵、电源、键盘、液晶显示等主要部分组成。单片机采集光强、湿度和温度信号,通过软件与事先设定的控制参数比较,并根据比较结果选择合适的灌溉方案程序,控制电机和水泵的启动,实现智能化灌溉。该系统可以广泛应用于户外植物及家庭花草栽培的自动浇灌。

This paper is to introduce a design of an intelligent watering device with display function, by taking single chip micyoco（SCM） as the core of the control, which has the function of selfregulation and control in accordance with the light intensity, humidity, computer, a light intensity sensor, humidity motor and pump, power, keyboard, LCD and temperature and other factors. It consists of a single - chip microsensor, temperature sensor, preamplifier circuit, A/D converter, other major parts. The device can irrigate intelligently with the cooperation of chip collecting light, humidity and temperature signal, through the software and the pre - set control parameters, and according to the result of the comparison selection of suitable irrigation program, control of motor and pump start. The system can be widely used in outdoor plants and family cultivation and automatic watering.
