【正文】 河南理工大學畢業(yè)設(shè)計（論文）說明書 I 摘 要 環(huán)境擁有自己的語言， 好的環(huán)境讓人 朝氣蓬勃， 相反不好的環(huán)境卻 讓人覺得情緒低迷。 而 居室環(huán)境 對一個人的影響也是很大的，因為每個人每天接觸最多的就是居室。對于居室環(huán)境而言，最重要的就是空氣。居室 空氣 作為 居室環(huán)境中的一大資源，它包圍著我們起居生活的方方面面 。一個環(huán)境的 通風、濕度以及溫度 給人帶來的舒適度是不一樣的，過熱、干燥、密閉、潮濕等環(huán)境會給人帶來負面的心 理 影響， 合理調(diào)節(jié)這些元素，將會 直接影響到我們健康生活的質(zhì)量。 隨著單片機技術(shù)以及數(shù)字技術(shù)快速發(fā)展，基于單片機的小型智能 家居監(jiān)控系統(tǒng)的發(fā)展已經(jīng)達到了一定的成 熟。 本系統(tǒng)是基于 Atmel89S52 單片機為 核心 處理器，配以外載多個溫濕度監(jiān)控模塊，對居室溫濕度進行檢測，并根據(jù)需要，向繼電器發(fā)送開關(guān)量，來控制 220V 電路的工作狀態(tài)， 220V 電路中的電 器 設(shè)備按照要求調(diào)節(jié)好，根據(jù)繼電器的通斷工作。除此之外，還有 GY30 光照模塊 對居室光照強度進行檢測。該系統(tǒng)設(shè)備簡單，成本低，能可靠的使用 ， 在居室、辦公室小型場合有很高的利用價值。 關(guān)鍵詞： 居室環(huán)境 溫濕度監(jiān)控 單片機 河南理工大學畢業(yè)設(shè)計（論文）說明書 II ABSTRACT Environment have their own language . A good environment make people vigor and vitality . Instead of bad environment make person feel emotional downturn . And bedroom environment exert a tremendous influence for a person . Because every day everyone in contact with bedroom environment is what most of the bedroom . As to the bedroom environment , the most important is the air . Bedroom air as a bedroom environment of a resource , it surrounds our daily life every aspect of life .ventilation, humidity and temperature of environmental bring fort is different . Overheating, dry, airtight, such as wet environment can bring negative psychological effect, Reasonable adjustment these elements , which will directly affect the quality of life and our health. With the rapid development of today39。s singlechip technology and digital technology, the development of small singlechip intelligent home monitoring system has reached a certain maturity. This system is why the Department of Atmel89S52 singlechip processor, with other than set out a number of temperature and humidity monitoring module to detect the room temperature and humidity, and, if necessary, sent to the relay switch to control the working status of the 220V circuits, 220V circuits electrical equipment in accordance with the requirements of regulation, according to the relays off. In addition, there BH1750 chip on the living room light intensity detection. The system equipment is simple, low cost, reliable use. High value in the living room, small office occasions.
