This system has found a feasible solution to further isolate people from garbage and prevent people from infecting bacteria. This paper designs multifunctional trash can control system based on STC89C52RC. This system has a simple structure, stable performance, convenient operation, and low cost. If the RPR220 photoelectric detects the full trash can, the system will give a voice prompt. When the ultrasonic sensor detects that the distance between the person and the trash can is less than the set distance, the trash can automatically flip the lid. Distance information is collected through the sensor, and then the single-chip computer sends instructions through AD conversion. It takes an ultrasonic sensor, RPR220 photoelectric sensor, and single-chip computer as the core. It comprises functional modules such as ultrasonic distance measurement, photoelectric sensor modules, motor drive modules, and voice alarm modules. It is also convenient and hygienic and has reliable performance, which helps you effectively prevent contact infections. The exquisite streamlined appearance sensor flip design, which combines infrared sensors and microcomputers, is flexible and convenient, and it can easily throw away garbage without manual or foot stepping. It is powered by a battery and has low power consumption. It does not require an external power source. As long as an object approaches the sensing area, the lid will automatically open, and the lid will automatically close after a few seconds after the object or hand leaves the sensing area. The smart and automatic bag-changing trash can is controlled by a circuit chip and consists of an infrared detection device and a mechanical, electronic drive system.
