When using an ordinary trash can, you have to step on it or open it by hand, which is neither convenient nor hygienic. The electronic sensor trash can make up for this defect. The smart sensor garbage bin has infrared sensing technology and the sensing distance is about 30cm. When people's hands or objects approach the sensing area about 30cm, the trash lid will open automatically. After the garbage is thrown into the trash, the lid of the trash can automatically shut down. Can effectively remove bacteria and odor.
