It is observed in past few years that urbanization increase largely and due to this there is a large increment in the waste production. Due to this the waste management becomes a very crucial topic in consideration. In this paper we introduce the concept of smart dustbin which uses the microcontroller for its operation. This smart dustbin uses Arduino microcontroller which is interfaced with ultrasonic sensor. The ultrasonic sensor is placed inside the dustbin which measures the status of the dustbin. The microcontroller Arduino is programmed in such a way that the empty part of the dustbin is displayed on the screen in terms of percentage of height. When the dustbin is completely full the display shows zero percent empty. After throwing waste people can reuse the dustbin. once the smart dustbins are implemented on the large scale by replacing the traditional dustbin. The waste can be managed properly because it can avoid the unnecessary lumping of waste on roadside. This smart dustbin can foul smell from these waste that remain untreated for a long time, due to negligence of authorities and carelessness of public may lead to long term problems. if the waste is not dump on at accurate time it introduce the new problems such as breed of insects, mosquitoes etc these insects create nuisance around unhealthy environment. It produces fearful diseases. This paper deal with Wet and Dry waste separately.
