详细说明: 基于单片机的烟叶烘烤过程温湿度报警系统(含proteus原理图和c源程序):在LCD1602上实时显示时钟,温度,湿度,系统运行时间。利用ds18b20检测当前温度,通过和设定参数的比较,给ISD1420发出报警脉冲,通过功率放大器LM386 驱动喇叭报警。-based SCM tobacco curing process temperature and humidity alarm system (including proteus diagram and c source ) : LCD1602 real-time display on the clock, temperature, humidity, the system running time. Ds18b20 detected using current temperature, and set the parameters, ISD1420 issued a warning to pulse through the power amplifier driving the loudspeaker warning LM386.
