基于单片机的智能垃圾桶设计

Design of intelligent trash can based on single chipmicrocomputerAbstract:As people's living standards are getting better and better,science andtechnology are constantly developing,and people's requirements for life are getting higherand higher.Everyone is yearning for better quality of life and attaches more importance toquality of life,especially for home life.Therefore,in this situation,there are a lot ofproducts about environmental health.In any place,garbage is undoubtedly the mosttroublesome thing,so the management of the trash can is very important,it is necessary todesign a smart trash product.And a lot of waste outside can also emit a pungent smell,polluting the environment and increasing the chances of contact with bacteria.The systemmainly includes alarm,trash status detection,human detection,indicator light,trash controland main controller.The system determines if there is someone by detecting the signal ofhuman body,and then controls the trash can to open.It can test the status of the trash can,determine whether the trash can is full,and give an alarm.Infrared tube module is selectedfor garbage full collection.Trash control select stepper motor,stepper motor drive selectULN2003.Select C language to design system software code,C language is simple to use,the editor select Keil,code writing,compilation,execution,complete the system functions,to achieve functional operation.Key Words:STC89C52 single chip computer;garbage bin control;ULN2003;infrared counterpart
