利用DS1302计时、DS18B20温度传感器检测温度、LCD1602显示。另有四个按键设置时间，日期，星期，温度报警上限和下限。并附有PROTEUS仿真文件。-Use DS1302 timing, DS18B20 temperature sensor detects the temperature, LCD1602 display. Another four buttons to set the time, date, week, temperature alarm upper and low

该方案通过AT89S52单片机读取实时时钟芯片DS1302和数字温度芯片DS18B20的内部数据，并进行处理后送到1602液晶显示来实现全部功能。-That clock mainly adopts the AT89S52 single-chip microcomputer as the main control core, provides clock through the DS1302 clock chip, collects and converts temperature through
