8、...............151自動(dòng)澆花系統(tǒng)的設(shè)計(jì)摘要：本設(shè)計(jì)是基于AT89C51單片機(jī)和ADC0832的自動(dòng)澆花系統(tǒng)。本設(shè)計(jì)的電路內(nèi)部包含濕度采集和AD轉(zhuǎn)換等主要功能。自動(dòng)澆水系統(tǒng)設(shè)計(jì)的澆水部分是通過單片機(jī)程序設(shè)計(jì)澆水的上下限值與感應(yīng)電路送入單片機(jī)的土壤濕度值相比較，當(dāng)?shù)陀谙孪拗禃r(shí)，單片機(jī)輸出一個(gè)信號(hào)控制澆水，高于上限值時(shí)再由單片機(jī)輸出一個(gè)信號(hào)控制停止?jié)菜?。這樣可以幫助人們及時(shí)地給心愛的盆花澆水。關(guān)鍵詞：AT89C51；濕度的采集
