【正文】 學(xué)實(shí)驗(yàn)中起到不可忽視的作用，發(fā)揮了它靈活輕巧使用方便的特點(diǎn)。并且在實(shí)現(xiàn)語音播報(bào)當(dāng)前溫度的同時(shí)，也實(shí)現(xiàn)了數(shù)字液晶顯示的功能，功能更形象使用更方便智能。 關(guān)鍵詞 單 片機(jī)； 溫度計(jì) ； 溫度傳感器 ； 設(shè)計(jì) Thermometer of Design Abstract Along with the time progress and the development, the monolithic integrated circuit technology already popularized to us lives, the work, the scientific research, each domain, will already bee one kind of quite mature technology, this article introduced one kind the digital thermometer which controlled based on the monolithic integrated design introduced the digital thermometer and the traditional thermometer pares, has the reading to be convenient, measured the warm scope is broad, measured warm accurate, its output temperature uses the numeral to demonstrate, mainly uses in to measured the warm quite accurate place, or the scientific research laboratory use, this design controller use monolithic integrated circuit AT89S51, measured the warm sensor uses DS18B20, this thermometer may adjust the demonstration date, the time, may establish, the maximum temperature lowly reports to the police the survey temperature surpasses the hypothesis the temperature bound, starts the buzzer and the indicating lamp reports to the police. The temperature demonstration is stable. The realization temperature demonstrated that, can above achieve accurately requests.
