Abstract

In this era of Science and Technology globalization, technology is really important because it can helps us to do any kind of work much easier. Besides that, technology is one of the best innovations to improve the management of recycle-based waste. Amount of waste day by day in Malaysia has increase because of lack of waste control and enforcement by the government. This has created an uncomfortable garbage scene where there is a lots of waste at the rubbish disposal site. This paper provides the automated and systematic Development of Waste Sorting with IoT (WSI). This development is able to sort different types of recycled waste using different types of sensors. The purpose of this work is to build a recycling container prototype based on a microcontroller by the use of two type of sensors that could gather various varieties of recyclable waste including metal, paper, and plastic. In addition, it automatically redirects waste to precise bin partitions by type. The construction of a recycling bin prototype contains methods of sensing. This sorting system used an Arduino Uno as a microcontroller to control input and the output of this waste sorting system. The sensing part detects type of waste including metal, paper, and plastic. Detecting metal type waste is done using a proximity sensor. As for paper detector, a Light Emitting Diode (LED) and a Light Dependent Resistor (LDR) sensor are used. The plastic-based waste is detected also using the same sensor that as the paper sensor which is Light Dependent Resistor (LDR). The differentiation between the plastic and paper is referred to the value of serial monitor that has been set in the coding. The Infrared Sensor Module is used to detect if there are any presence of waste in the dustbin. Observation have been made for this waste sorting system and normal system. This waste sorting system shows that it is more convenient and practical compared to normal system. The results of this work show that this waste sorting system prototype is able to isolate the waste successfully and it is highly potential to be used in the future.
