温度报警器
说明: 1.系统整体设计
系本设计采用STC89C52单片机为主控芯片,结合外围电路矩阵键盘、液晶显示器LCD1602等部分组成,能够实现:
1 DS18B20不断采集周围环境温度;
2. 单片机处理温度的数据显示在DS18B20;
3. 用户设定温度报警的上限和下限;(1. Overall design of the system
This design uses STC89C52 single chip microcomputer as the main control chip, combined with peripheral circuit matrix keyboard, liquid crystal display LCD1602 and other parts
DS18B20 continuously collects the ambient temperature;
2. The temperature data processed by MCU is displayed in DS18B20;
3. The user sets the upper limit and lower limit of temperature alarm;)
