摘要
本篇论文主要通过DS18B20做传感器来测量温度，以及通过它来设置温度的上下限。首先是对DS18B20的深入了解并根据DS18B20的内部结构特点来设计硬件电路和软件程序。因考虑到在设置温度TH和TL所以本次设计采用四个按键来控制，通过按键之间的协调作用来完成温度设置值，由于温度的不同我们采取不同的信息来作为信号处理，所以在硬件电路中用蜂鸣器来报警做为提醒。我们采用1602液晶显示所测出来的温
This paper DS18B20 done mainly through sensors to measure temperature, and through it to set the temperature of the upper and lower limits. DS18B20 is the first in-depth understanding of and in accordance with the internal structure of DS18B20 to design hardware and software. By taking into account the temperature settings TH and TL So this design uses four buttons to control, through the coordinating role between the keys to complete the temperature setting values, as we take the temperature of different information to different as signal processing, hardware Circuit used as a warning to remind the buzzer. We use 1602 LCD measured by the temperature.Keywords DS18B20 1602 LCD display schematics and procedures28
