Ultrasonic Sensor based Smart Dustbin for Real Time Monitoring and Action
Year: 2026
Type: conference-paper
Abstract: Due to population increase in cities, public waste have become a big problem. Such problem demands a smart dustbin solution. This study shows a POC of a smart dustbin that uses ultrasonic sensors and interactive UI for status report and user interaction and experience. Our solution has two main HC-SR04 units: one for continuous readings dustbin filled height and one to detect user distance from the dustbin. The $1^{\text {st }}$ sensor feeds data to a $16 \times 2$-character LCD, which tells us the filled level of dustbin. There is one more sensor that commands the servo to swing the lid of the dustbin to open it when someone is within the range of 20 cm, therefore it also prevents the user hand contact with the dustbin. There is An ESP32 micro-controller that contains whole software setup and firmware which is written in embedded C and compiled in Arduino IDE environment. Out tests and trials have shown that each module operates perfectly as per the POC with the waste sensor reporting correct levels and the lid sensor working fine. We advice to deploy this dustbin in high-footfall venues such as urban parks, where it can be used with various smart devices and help other workers and sanitation staff.
