Garbage Overflow is the primary source of contamination in the current situation. It results to unhygienic conditions for the populace and foul odors in the neighborhood, which spreads some deadly diseases & human illness. We are planning to implement a project called IoT Based Waste Management Using Smart Dustbin to prevent all these scenarios. With the aid of the IoT idea, implementation is carried out. Ordinary trash cans need to be opened by pushing a foot against a lever before being filled with trash. In order to empty it and prevent overflow, one must also keep note of when it is full. Here, we suggest a clever trash can that takes care of everything on its own. Our device opens instantaneously by detecting human face. Every trash can in the city will have a distinct ID, making it easy to tell which one is full. Several trash cans are positioned all throughout the city or campus in this arrangement. These trash cans have sensors built in to them that help keep an eye on their depth and level. The device will transmit the reading to a device together with the provided unique ID when the level of the bin exceeds the threshold limit. The user won't have access to the bins once they are full. When this happens, the trash can produce audible alerts and uses an LCD display to reveal the location of other garbage cans nearby. Using the Internet, the relevant authorities can monitor the condition of the bin from any location, and an immediate action will be taken to swap out full bins for empty ones
