Currently, environmental protection stands on a significant position. The purpose is to solve the problems that restrict the development of cities, such as the untimely disposal of garbage, the incomplete classification of kitchen waste and other recyclable garbage, and the inefficiency of sanitation workers. At present, a common garbage bin in use just carries a single and limited function, and the applied intelligent garbage bin has a disadvantage of high mechanical consumption. It needs to consume more energy of environmental sanitation workers, and garbage classification depending on human labor is inefficient. However, my research object is a kind of intelligent garbage bin based on Narrow Band Internet of Things (NB-IoT) technology, which is different from an ordinary garbage bin. It adds a garbage detection and classification function based on Internet of Things perception system, through infrared senson’s, odor sensors to achieve various functions. It uses NB-IOT communication module to transmit information. This new intelligent garbage bin can make the sanitation workers gain the information whether the rubbish becomes full and whether the rubbish is poisonous or not.
