Main Article Content
Abstract
The Smart Dustbin is a smart sensor-embedded waste management product which is going to help resolve problems with increasing solid waste management and disposal in urban areas. In this paper, we will describe the designing, developing and testing of the first version of Smart Dustbin that incorporates a HC-SR04 ultrasonic distance sensor, a SG90 servo motor and an Arduino Uno board. The project enables users to use the Smart Dustbin without touching its lid using an ultrasonic distance sensor to detect when waste has been placed at or below 20cm from the base of the bin. Once the sensor detects waste near the bin, it activates the servo motor to open the lid, and keeps it open for some time after opening then closes. After completing all stages of Human-Centred Design Thinking process including Empathise, Define, Ideate, Prototype and Test the prototype of Smart Dustbin was tested in a School Corridor and Residential Apartment. The results of testing demonstrated very positive responses from users towards aspects of hygiene, usability, and efficiency. In addition to the description of hardware design, circuit design and Arduino Code of the Smart Dustbin prototype, we have provided suggestions on potential developments to be made on the project including Solar Power Integration into the Smart Dustbin, Artificial Intelligence based Waste Sorting and connection to Municipal Dashboard.
