Traditional control methods "Micro Cooling Fan" can not satisfy the needs of social development. Low fan prices, relative to the air-conditioning is concerned, more likely to be accepted by the majority of the people, the designed intelligent fan, all from the comfort of people's view, is a with the temperature control fan speed automatically size, automatic New Intelligent switching function "Micro Cooling Fan". In PIC16F1936 microcontroller as the main chip design fan of automatic control system, using DS18B20 digital thermometer for temperature testing, infrared receiving control signals to achieve the "Micro Cooling Fan" control in the design of the system to join the voice control system Shihai They can work on their own according to the command issued by the operator.
