Human-computer interactive intelligent trash can

With the demand for epidemic prevention and control and the encouragement of garbage recycling policy, how to enable users to empty garbage at the moment of garbage can idleness, timely disposal of some garbage that may become a medium of virus transmission and effective management and disposal of garbage cans become a problem worthy of attention. Therefore, this paper designs a smart trash can based on the STC89C52 microcontroller. This smart garbage can realize the functions of automatic opening of the lid by a garbage can personnel identification, real-time display of garbage capacity inside the garbage can, and human-computer interaction display by Bluetooth APP, which can effectively reduce the phenomenon that person needs to wait when emptying garbage, and also improve the efficiency of garbage can management for the administrator, and can provide the administrator with a suitable decision plan for when and where to put how many garbage cans.
