DS18B20 温度传感器读数据源程序

系统由中央控制单片机、温度检测器、时钟系统及显示器部分组成。控制器采用单片机AT89C51，温度检测部分采用DS18B20温度传感器，时钟系统用LED作为显示器。 单片机对数据处理后显示时间；温度传感器DS18B20采集温度信号送该给单片机处理，再把时间数据和温度数据送七段LED显示器显示，该系统还具有限温控制，当温度高于或低于某一给定温度值时分别有红灯和绿灯点亮提示，并伴随着蜂鸣器声音提示。本系统同时具有调节高低温上下限，时间调节功能-DS18B20 source temperature sensor reading data from the central control system, single-chip, temperature detectors, clock systems and display components. Single-chip computer controller AT89C51, temperature detection part of the use of DS18B20 temperature sensor system using LED as a clock display. Single-chip data processing for the time after the show　DS18B20 collecting temperature sensor to send the temperature to the single-chip signal processing, then the time to send data and temperature data display Seven-Segment LED display, the system also has a limited temperature control, when the temperature is higher than or below a given temperature value of the respective red and green light prompts and tips along with the buzzer sound. At the same time, adjustment of the system with upper and lower limits of high and low temperature, the time adjustment function
