摘要
普通风扇存在温度控制不灵活、操作不便等问题。因此，此次设计了一款具有多种控制模式的智能风扇，实现了以下功能：首先，通过DS18B20温度传感器对环境温度进行监测，使风扇能够根据实际温度情况自动调节转速。其次，智能风扇拥有自动模式。用户可以通过按键设置三个温度阈值。当环境温度低于下限值时，风扇停止工作，保持静音状态；当温度介于下限值和中限值之间时，风扇低速转动，保持舒适微风；当温度介于中限值和上限值之间时，风扇中速转动，为用户提供适度的风力；当温度高于上限值时，风扇高速转动，确保有效降温。
此外，智能风扇还支持手动模式，用户可以通过按键手动调节风扇的转速，灵活自如地控制风力大小。为了提升用户体验和便利性，智能风扇还配备了红外遥控模式和蓝牙遥控模式。用户可以使用配套的红外遥控器或通过蓝牙模块连接手机，远程控制风扇的转速和模式选择，使控制更加智能化和便捷化。最后，智能风扇采用LCD1602液晶显示屏，实时显示当前环境温度和风扇的转速档位，方便用户了解当前状态。
通过以上功能的实现，本设计提高了普通风扇的智能化水平和用户体验，为用户提供更加舒适、智能的风扇使用体验。

Abstract
The conventional fan faces issues such as inflexible temperature control and inconvenient operation. Therefore, this design introduces an intelligent fan with multiple control modes, implementing the following functionalities: Firstly, by using the DS18B20 temperature sensor, the fan can automatically adjust its speed based on the actual temperature. Secondly, the intelligent fan features an automatic mode, allowing users to set three temperature thresholds via buttons. When the ambient temperature is below the lower limit, the fan stops operating, maintaining a silent state. When the temperature falls between the lower and middle limits, the fan operates at a low speed, providing a comfortable breeze. When the temperature falls between the middle and upper limits, the fan operates at a medium speed, offering a moderate airflow. Lastly, when the temperature exceeds the upper limit, the fan operates at high speed, ensuring effective cooling.Additionally, the intelligent fan supports a manual mode, allowing users to manually adjust the fan’s speed through buttons, providing flexible control over the airflow. To enhance user experience and convenience, the fan is equipped with both an infrared remote control mode and a Bluetooth remote control mode. Users can use the provided infrared remote control or connect their smartphones via a Bluetooth module to remotely control the fan’s speed and mode selection, making the control more intelligent and convenient. Lastly, the intelligent fan incorporates an LCD1602 liquid crystal display, which continuously shows the current ambient temperature and the fan’s speed level, enabling users to stay informed about the current status.
Through the implementation of these features, this design enhances the intelligence level and user experience of conventional fans, offering users a more comfortable and intelligent fan usage experience.
