摘要
此次设计一款通过检测温湿度自动控制风扇转动的系统，该系统采用STC89C52单片机作为此次设计的核心控制模块，采用温湿度检测模块DHT11对当前环境中的温湿度进行实时监测。在进行温湿度的设置过程中，用户可以按照自己的需求设置的温湿度的上下限值，当系统正常进行工作时，通过DHT11检测模块检测周围环境的温湿度；如果检测到环境的温度高于设置的最大值，则风扇高速转动，如果检测到环境温度在用户设置的最大值到最小值之间，风扇低速转动，当检测到环境的温度小于设置的最小值，风扇停止转动；如果检测到环境的湿度高于设置的最大值，则风扇高速转动，如果检测到环境湿度在用户设置的最大值到最小值之间，风扇低速转动，当检测到环境的湿度小于设置的最小值，风扇停止转动。经过实物测试，此次设计的系统控制较为准确，且工作较为稳定。

Abstract
The design of a fan rotation automatic control system through the detection of temperature and humidity, the system uses STC89C52 microcontroller as the core control module of the design, using the temperature and humidity detection module DHT11 real-time monitoring of the temperature and humidity in the current environment. When setting the temperature and humidity, you can set the upper and lower limits of the temperature and humidity as required. When the system is running properly, the DHT11 detection module detects the ambient temperature and humidity. If the ambient temperature is between the maximum value and the minimum value, the fan rotates at a high speed. If the ambient temperature is between the maximum value and the minimum value, the fan rotates at a low speed. If the ambient temperature is lower than the minimum value, the fan stops rotating. If the ambient humidity is between the maximum value and the minimum value, the fans rotate at a high speed. If the ambient humidity is between the maximum value and the minimum value, the fans rotate at a low speed. If the ambient humidity is less than the minimum value, the fans stop rotating. After the physical test, the design of the system control is more accurate, and the work is more stable.
