Abstract: This design to MSP430F149 microcontroller as the core control module, the HS0038 photoelectric sensor and DS18B20 temperature sensor to measure the speed of the electric fan and testing time, through the master-slave SCM environment temperature of munication between plete the electric fan speed data processing, pattern control and speed control and so on, USES the PWM pulse modulation technology to control the speed of the fans, use the keyboard and HB12864 liquid crystal display to realize human-machine interaction, with infrared emission and accept device plete remote sensing control function. The system has the fan stepless speed regulation, and to the electric fan speed setting and speed of the real-time testing and display, with the wind, such as natural sleep DuoZhong work models to choose, can show the date, time, temperature, fan speed, the mode of operation and so on information and realize the automatic shutdown open, such as timing function, system structure is simple, step into small, high precision of advantages.
