本设计主要用数字式温度传感器DS18B20来采集外界温度，该设计硬件部分核心器件为89S52单片机。通过编写大量C语言程序来支撑单片机来实现温度接收、转换、存储和显示等，最终温度通过数码管显示出来。软件方面通过二个智能板通过RXD、TXD通信，一个智能板显示温度值，通过RXD发送到另一个智能板上并显示。-Designed primarily with the digital temperature sensor DS18B20 to collect outside temperature, the design of the hardware part of the core device for single-chip 89S52. Through the preparation of a large number of C language program to support single-chip receiver to achieve the temperature, conversion, storage and display and so on, eventually the temperature through the digital tube display. Software through the adoption of smart plate 2 RXD, TXD communications, a smart board display temperature through RXD Send to another smart board and displayed.
