概述 很多人喜欢养花 ,但是总是养不好,经常能听到这样的对白:哎···最近又把花养死了,真是罪过,罪过······。每当听到这样的话你有没有想过 问题出在哪里呢?究其原因无非就是无法确切知道土壤湿度,给花草浇适量的水,要么浇太多了,要么浇太少了导致花草死掉。本文将介绍如何DIY一套智能花园浇水系统,能实时检测土壤湿度,自动给花草浇水,帮助你养出更多别致的花草。 工作原理 给系统上电后,首先会进行系统初始化,初始化完成Arduino会实时读取按键标志位。如果按键标志位是0,读取当前土壤湿度值,当土壤湿度低于土壤湿度临界值,打开电池阀开始浇水,直到土壤湿度高于土壤湿度临界值再关闭电磁阀停止浇水;如果按键标志位是1,进入修改土壤临界值提示页面;如果按键标志位是2,读取编码器脉冲数;如果按键标志位是3,确认修改土壤临界值。 硬件 智能花园浇水系统主要包括五大部分,分别是控制部分、检测部分、显示部分、调节部分、浇水部分。下面将对每一部分详细介绍。 1 控制部分 智能花园浇水系统我们用Arduino UNO为控制核心,在整个系统中扮演着最重要的角色,它就像一个人的大脑,起着支配身体其他部分的作用。 2 检测部分 我们用YL-69土壤湿度传感器作为检测部分,用于检测土壤湿度,该模块规格如下 输入电压 3.3V-5V 输出电压 0-4.2V 输入电流 …Read the Rest
