电子式温度计因为其方便的度数和较为稳定的物理特性，测量范围广抗击

打能力等受到人们的青睐。本次试验设计采用了市场上极为普遍的 AT80C51

系列芯片做主机，采用共阳极四位八段数码管显示，采用美国 dallas 公司

生产的 DS18B20 作为温度采集的传感器，节省去了温度校正的环节。而

18B20 也增加了温度的可靠性。此外试验产品采用五伏直流电源供电，电源

old-fashioned thermometer is fade from life. Electronic thermometer

because of its convenience and relatively stable degree of physical

properties, measurement range and strong Stability by people of all

ages. The trial was designed with an extremely popular on the market

do a host chip AT89C51 series, eight out using four common anode LED

display, using the U.S. as dallas produced DS18B20 temperature sensor

acquisition, saving to a temperature correction factor. And 18B20

also increases the reliability of the 5 temperature. In addition,

test products with five-volt DC power supply, power supply simple.

Can be used as greenhouses, bathrooms, libraries and other occasions

Keywords: 51 single DS18B20 electronic thermometer.

也都必须用到单片机：
