【正文】 2桂林電子科技大學訓(論文)報告用紙 第 2 頁 共 2頁傳感器綜合設(shè)計實訓(論文)說明書 題 目: 光敏電阻檢測光照亮度 院 (系): 力學與光電物理學院 專 業(yè): 應(yīng)用物理學 姓 名: 江運 學 號: 2014305066 指導教師: 李洋 2012年6月20號 摘 要本設(shè)計題目是光敏電阻測量光照強度,用光照的強弱來改變光敏電阻的阻值大小,從而使輸出電壓值改變,通過測量輸出電壓值的大小就可以間接的測量光照的強度了。本設(shè)計有光照強度報警控制系統(tǒng)和光照強度等級顯示電路以及光照亮度的顯示。本設(shè)計采用了STC單片機為主控制電路,用數(shù)碼管顯示光照強度值,用綠、黃、紅LED來顯示光照亮度等級,用蜂鳴器來做報警電路。本設(shè)計電路各個部分電路的設(shè)計原理及功能都能實現(xiàn),要求對各種基本的電子元器件,電阻、電容、二極管、三極管等熟悉,掌握Proteus 仿真軟件的運用、Protel 99 SE工具軟件等繪圖軟件,并加以運用。用單片機內(nèi)部的AD轉(zhuǎn)換實現(xiàn)模擬轉(zhuǎn)化為數(shù)字量,通過編程控制各個外圍電路并實現(xiàn)其功能。本設(shè)計具有有線路簡單、結(jié)構(gòu)緊湊、價格低廉、性能優(yōu)越等特點。關(guān)鍵詞:光照強度;光敏電阻;單片機 Abstracts This design is entitled to the photoresistor to measure light intensity, the strength of the light to change the photosensitive resistor size, so that the output voltage changes, by measuring the size of the output voltage value can be indirectly measuring the light intensity. The design of the light intensity alarm control system and the light intensity level display circuit and illumination brightness of the display. This design uses the STC microcontrollerbased control circuit, digital display light intensity, light green, yellow, red LED display brightness levels, to do with buzzer alarm circuit. The design of the circuit design principles and functions of various parts of the circuit can achieve, requiring a variety of basic electronic ponents, resistors, capacitors, diodes, transistors and other familiar and master the use of Proteus simulation software Protel 99 SE software tools such as mapping software and use of them. AD of the internal microcontroller to convert analog into digital, programmed to control the
