單片機(jī)溫度報(bào)警器設(shè)計(jì)論文-文庫(kù)吧在線文庫(kù)
【正文】 在短時(shí)間內(nèi)機(jī)房溫度升高超出設(shè)備正常溫度，導(dǎo)致系統(tǒng)癱瘓或產(chǎn)生火災(zāi)，這時(shí)溫度報(bào)警系統(tǒng)就會(huì)發(fā)揮應(yīng)有的功能。 Therefore the tele room belongs to electronic products fever faster, in a short time, room temperature beyond normal temperature, cause the system equipment or produce fire, then paralyzed temperature alarm system will play its function.This paper is to use temperature sensor DS18B20 temperature alarm, automatic measuring current environmental temperature by a single chip microputer AT89C2051 control, and through three seven segment digital pipe display, if the current environmental temperature over this temperature, system warning.Keywords:Microcontroller Temperature alarm Temperature sensor leds Temperature display 一、功能說(shuō)明該溫度報(bào)警器電路是由18B20溫度傳感器作為溫度傳感器材，由AT89C2051 單片機(jī)進(jìn)行數(shù)據(jù)處理。C時(shí)，報(bào)警發(fā)光二極管發(fā)光，同時(shí)繼電器動(dòng)作。8三、電路原理圖 四、元件清單名稱規(guī)格編號(hào)主要功能或作用按鈕6X6X5ANANAN3調(diào)節(jié)報(bào)警溫度的值電容30pCC2單片機(jī)時(shí)鐘振蕩電容10μFC3單片機(jī)復(fù)位電容470μFC4電源濾波電容104C5電源濾波單片機(jī)AT89C2051IC1CPU溫度傳感器DS18B20IC2溫度傳感器穩(wěn)壓塊L7805IC3電路工作于
