摘 要
课题主要任务是设计一款基于单片机的自动晾衣架。主要通过各个传感器收集模拟信号发送到单片机，单片机发出指令到各个模块输出数字信号。通过温湿度，雨量，风速，光照信息的采集来判断是否满足晾晒条件来进行衣物的晾晒。
该系统包括单片机、电源部分、温度湿度光强风速采集部分、显示部分、控制执行部分等。能够实现衣服的自动晾晒。本设计在设计时采用了STC89C52单片机的芯片作为核心，由温湿度传感器DHT11，光敏电阻、雨量检测、风速检测、LCD1602显示屏以及步进电机ULN2003等组成。用户需要做的只是将衣服放于衣架上，通电便可以享受到非常好的晒衣体验。当湿度低于设定阈值收回，当湿度达到设定的阈值时晾衣架伸出；温度小于设定值时晾衣架收回；光照强度过低时晾衣架收回，光照强度较高时时晾衣架伸出；风速较大时晾衣架收回等功能。

Abstract
The main task of the subject is to design an automatic clothes hanger based on the microcontroller. The analog signals are collected by various sensors and sent to the microcontroller, and the microcontroller sends instructions to each module to output digital signals. Through the collection of temperature and humidity, rainfall, wind speed, and light information, it can be judged whether the clothes meet the drying conditions.
The system includes single-chip microcomputer, power supply, temperature, humidity, light intensity, wind speed acquisition, display, control execution, etc. It can realize automatic drying of clothes. This design uses the chip of STC89C52 as the core, which is composed of temperature and humidity sensor DHT11, photosensitive resistor, rainfall detection, wind speed detection, LCD1602 display screen and stepper motor ULN2003. All users need to do is to put their clothes on the clothes rack, and then they can enjoy a very good drying experience. When the humidity is lower than the set threshold, the clothes rack will stretch out when the humidity reaches the set threshold; When the temperature is lower than the set value, the clothes hanger will be retracted; When the light intensity is too low, the clothes hanger will be retracted, and when the light intensity is high, the clothes hanger will stretch out; When the wind speed is high, the clothes hanger can be retracted.
