摘要
本文以PIC单片机为核心,采用美国DALLAS公司的数字式温度传感器DS18B20,设计了一种最简的温度测量系统,文中介绍了PIC单片机和温度传感器DS18B20,以及温度传感器DS18B20的工作时序,并且提出了最简温度测量系统的硬件电路和软件程序设计的方案,给出了PIC单片机和DS18B20的初始化程序,以及对DS18B20读、写等相关程序,实现了对测量环境温度的采集和显示,并且该系统结构简单、抗干扰能力强、适用范围广,且易于扩展。
This paper introduces the Min-temperature Measurement System based on PIC and DS18B20.The Single Bus Digital Temperature Sensor DS18B20 of US Semiconductor Company DALLAS and the PIC of 18F are used in this system as kernel and controller respectively.The paper designs the hardware and software of the system,the program of communication between PIC and DS18B20,and realizes to collect and display the temperature.This system has the character of more simple structure,stronger anti-jamming ability and wider application.
