基于AT89C2051数字温度计的设计

AT89C2051-based design of a digital thermometer

基于AT89C2051单片机为核心,结合温度传感器,来设计数字温度计.能适时测量外界环境温度,并通过两个数码显示管把所测温度显示出来,通过改变(矫正)滑动变阻器的阻值对温度进行微调.测试系统具有结构简单、稳定可靠的优点,适用于对测量温度精度要求不是非常高的环境.

The design is based on the AT89C2051 with the single-chip microcomputer as the core.Combined with the temperature sensor,a digital thermometer has been designed.The thermometer can timely measure the outside ambient temperature.Through two digital displays the measured temperature is displayed,by changing the resistance value of the sliding rheostat（correction） for temperature tuning.The test system,has the simple structure,of the stable and reliable advantages,and can be widely used in the environment which does not require high temperature measurement accuracy.
