The thickness of 304 stainless steel is 1.0mm, and the surface can be spray-painted with color (gray or green optional to blend with the community environment); a smart sensor door is installed on the front (sensing distance 0.5m), so there is no need to open the door manually when placing garbage to avoid contact contamination. There is an internal trash can overflow sensor that sends clearing reminders through the community property APP to reduce garbage accumulation; a solar LED light is added to the top to provide lighting for placing garbage at night; the size (length × width × height) is 2.8 × 1.4 × 2.1m, which is suitable for the community green belt and the entrance of the unit building.
