【摘要】 在Proteus环境下,使用MCS-51单片机检测多个DS18B20温度传感器传回的温度信号,并对各个温度传感器设置温度超限声光报警。重点介绍在Proteus环境下如何读取DS18B20温度传感器的64位ROM序列号,并详细阐述单总线挂多个温度传感器时控制程序的设计过程。更多还原

【Abstract】 In the Proteus environment,MCS-51 microcontroller was used to detect temperature return signal of multiple DS18B20 temperature sensor,and each of the temperature sensors is set temperature transfinite acousto-optic alarm. This paper focuses on how to read 64 ROM serial numbers of DS18B20 temperature sensor in the Proteus environment. The process of program design for multi temperature sensors attached to 1-wire was elaborated.更多还原
