摘要
介绍了单总线数字温度传感器DSI8B20和ZY1420秒高保真语音录放模块的特性,利用DS18B20和ZY1420设计了一种基于AT89C51单片机的智能温度报警系统。该智能温度报警系统以ATMEL公司生产的AT89C51为控制器,结构简单、测温准确。软件使用模块化结构.并对温度进行刷新显示和报警处理。
This paper introduces the single-bus digital temperature sensor DSI8B20 and the high-fidelity voice recorder module ZY 1420 and their application in an intelligent temperature alarm system based on the single-chip microcomputer AT89C51. The hardware and software of the system are also outlined.
