【正文】 下AN3，先顯示上次存貯下來的設(shè)定溫度（報(bào)警控制）值，然后再顯示環(huán)境溫度值，并隨環(huán)境溫度的變化而變化；③再按一下AN3，溫度數(shù)字閃爍，待調(diào)節(jié)；④接著按AN1或AN2：按AN1為報(bào)警溫度值變大，最大為125186。C時(shí)，報(bào)警發(fā)光二極管發(fā)光，同時(shí)繼電器動作。C之間，精度為1186。 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。 Electrostatic generation high temperature or fire。造成高溫火災(zāi)有：電氣線路短路、過載、接觸電阻過大等引發(fā)高溫或火災(zāi)；靜電產(chǎn)生高溫或火災(zāi)；雷電等強(qiáng)電侵入導(dǎo)致高溫或火災(zāi)；最主要是機(jī)房內(nèi)電腦、空調(diào)等用電設(shè)備長時(shí)間工作，導(dǎo)致設(shè)備老化，空調(diào)發(fā)生故障，而不能降溫；因此機(jī)房內(nèi)所屬的電子產(chǎn)品
