Several studies and reports of a smart dustbin are out there to reduce human efficiency and to make the city clean. Here, we will be using the idea of a smart dustbin using IoT and different sensors and work on it to make it even more effective. Each dustbin shall have the data of the distance and the filled percentage of all other dustbins, aligned to it, in its memory. When it’ll be filled up to 75% or 90%, which we’ll know by the Ultrasonic Sensor, it’ll send a signal to the municipality about its content. When the dustbin shall be 100% filled, it’ll send a signal to the municipality to empty it. The now brimmed dustbin shall display a message on the attached LCD of the nearest dustbin which is not full, along with the distance and the direction in which it resides. The dustbin calculates the closest distance from the data saved in the memory and at the same time checks if the other dustbins are filled completely or not. If both the conditions match, it displays the number and direction of that dustbin. This implementation is introduced so that people don’t dump their trash in front of the filled dustbin, rather find a nearby one. This framework helps to make the city clean in an effective way.
