An intelligent fan system were designed based on STM32,in order to address inadequacy of the conventional fans in automatic speed adjustment.STM32 is used as the main control chip of the system.The display of LCD1602 and the working mode of the fan motor are controlled,according to the environment temperature information detected by DS18B20 and the input instruction of LU-ASR01 voice module.The system provides three kinds of human-computer inter-action scenarios,such as key adjustment,temperature control and voice control.In this paper,the working principle and design method of the intelligent fan system are described in detail.Meanwhile implementation of hardware and software design are outlined.The result of functional test shows that the proposed design is feasible and can meet the demand of in-telligent fans.
