MICROCONTROLLER-BASED METAL AND NON-METAL SORTING AUTOMATIC TRASH CAN COVER

Abstract

Waste is still a problem that is often faced in the community, the accumulation of waste in the environment must be
overcome with good management, because if not it will have a negative impact on all components of life. Waste
problems still often arise due to the habits of people who still throw garbage out of place, so that the existingarbage
becomes scattered in several places that cause a very pungent odor, even triggering flood disasters. The problem
that is difficult to handle is the placement of metal and non-metal waste, if the two wastes are mixed, it is difficult to
manage the two types of waste. One solution that can be applied to the trash can is to make a trash can that can
separate the location of waste according to its type, namely metal and non-metal. The innovation of a trash can that
can detect objects and the cover automatically opens, then the garbage will be sorted into metal and non-metal
waste based on a microcontroller aims to provide convenience to everyone who will throw away garbage by
automatically separating the types of waste. Using the processing module in the form of arduino nano as the
processing center, the sorting module in the form of an inductiv proximity sensor as a metal or non-metal detector,
the object detection module in the form of an ultrasonic sensor as a distance detector, the drive module in the form
of a servo motor as a garbage cover drive and a metal and non-metal garbage separator bar drive. A healthy
environment will encourage people to live healthy and realize a clean environment by creating a sense of "concern"
for the importance of environmental cleanliness and body health without waste
