Garbage Bin Alert System Using Arduino UNO for Smart Cities

Abstract

The human population is rapidly expanding, posing a significant challenge to waste management systems and, as a result, to keeping the environment clean and green. Many cities around the world are in jeopardy as a result of this issue. We are implementing a smart dustbin employing IoT devices such as Arduino UNO, ultrasonic sensor, gas sensor, humidity sensor, PIR sensor, servo motor, GSM module, and GPS modem to avoid waste overflow from the dustbin, separation of dry and wet rubbish, and also to stop unsanitary conditions. In our paper, we presented an innovative smart dustbin that sends notifications to responsible authorities when the garbage level is reached or if it generates a strong odour, resulting in a more effective and efficient garbage disposal system as well as the ability to solve the problem of dry and wet garbage separation. When motion is detected inside the defined sensor range, the designed system immediately sends an alarm message to the mobile phone.
