随着社会的发展，环保问题越来越受到人们的重视。因此，回收旧衣物也成为了一项重要的任务。针对这个问题，我们设计了一款基于单片机的旧衣回收箱，旨在让回收箱变得更加智能和安全。该设计采用了MQ-2烟雾传感器来检测回收箱内烟雾值。当烟雾值超过设置的最大值时，系统会自动发出声光报警，并开启水泵进行灭火，同时还会发送短信提醒用户回收箱发生了火灾，让用户可以第一时间得知情况并采取相应措施。此外，该回收箱还具有智能识别功能，可以根据旧衣的材质和种类进行分类，方便后续处理和回收。同时，回收箱内还配备了LED灯光，方便用户在夜间投放旧衣物。通过这款基于单片机的旧衣回收箱的设计，我们可以有效提高回收箱的智能化程度和安全性，同时还可以方便用户对旧衣进行分类和投放。相信在未来，这种回收箱会成为社会发展的必需品，为环保事业做出更大的贡献。

With the development of society, people pay more and more attention to environmental protection. Therefore, recycling old clothes has also become an important task. To solve this problem, we designed a used clothing recycling box based on single chip microcomputer, aiming to make the recycling box more intelligent and safe. The design uses an MQ-2 smoke sensor to detect the smoke value in the recycling box. When the smoke value exceeds the maximum value set, the system will automatically issue a sound and light alarm, and turn on the pump to extinguish the fire, and will also send a text message to remind the user of the fire in the recycling box, so that the user can know the situation and take corresponding measures in the first time. In addition, the recycling box also has an intelligent identification function, which can be classified according to the material and type of used clothes, so as to facilitate subsequent processing and recycling. At the same time, the recycling box is also equipped with LED lights, which is convenient for users to put old clothes at night. Through the design of the used clothes recycling box based on the single chip computer, we can effectively improve the intelligence and safety of the recycling box, and also facilitate users to classify and put old clothes. It is believed that in the future, this recycling box will become a necessity for social development and make greater contributions to the cause of environmental protection.
