基于stc89c52rc的单片机c程序。运用ds18b20采集温度。单片机采集温度，并产生相应的PWM信号控制风扇运行。-Based on stc89c52rc microcontroller c program. To use ds18b20 acquisition temperature. Microcontroller to capture temperature, and generates the appropriate PWM signal to control fan operat

单片机用1602 lcd与ds18b20设计的温度报警器程序，虽不可仿真，但可参考-Canopy temperature control system design and implementation
