基于单片机的多功能电子时钟的设计
资料介绍
提出了一种基于单片机的多功能电子时钟的设计方法,以AT89C52单片机作为系统的主控芯片,采用DS1302作为时钟控制芯片,实现日期时钟显示并且提供精准定时的功能。此外,还可经由DHT22所构成的温湿度传感电路,将温湿度参数输入到单片机中进行处理,然后通过液晶显示电路将所有的结果显示出来。结果表明该电路能精确的显示时钟以及各种环境参数,并能实现闹钟、定时开关和温湿度阈值报警等功能,效果良好。
A design method of multi-function electronic clock based on MCU is proposed. AT89C52 MCU is used as the main con. trol chip of the system and DS1302 is used as the clock control chip to realize the display of date and clock and provide precise tim. ing function. In addition, through the temperature and humidity sensor circuit composed of DHT22, the temperature and humidity parameters can be input into the MCU for processing, and then all the results can be displayed through the LCD display cir. cuit. The results show that the circuit can accurately display the clock and various environmental parameters, and can realize the alarm clock, timing switch and temperature and humidity threshold alarm functions, with good results.
