本设计采用一块单片机（AT89S52）作为多功能数字钟的控制核心，加以温度传感器、红外接收管、蜂鸣器、液晶显示器（LCD1602）、电源电路及其他电路构成。实现了时间设置、闹铃设置、闹铃开和关的功能；LCD显示小时、分钟，有AM、PM指示灯，闹钟就绪灯，闹钟到点蜂鸣器报警，220V供电基本功能。另外，本设计还实现了通过切换键盘显示现场温度，红外停止闹铃的功能。
-This design uses a single chip (AT89S52) as the core controller of a multi-functional digital clock,complemented by temperature sensor,infrared receiver,buzzer,liquid crystal display(LCD1602),power circuit and other circuit. It implementes time setting,alarm setting,and alarm on/off functions.Moreover, it has some basic functions such as displaying hour and minute,AM/PM indicator light,alarm clock ready light,buzzer alarm and 220V power supply.In the end,this design also can show the scene temperature through switching the keyboards,and stop the alarm by infrared circuit.
