Bottle-SegreDuino: An Arduino Frequency-Based Bin for Tin Can and Plastic Bottle Segregation using an Inductive Proximity Effect
AI summary Read the abstract
This is an engineering project describing the development of an Arduino-based frequency-sensing bin that can automatically sort tin cans and plastic bottles for recycling. It is a technology development project rather than a primary research article.
In the current scenario, waste disposal has become a major problem owing to increasing urbanization, industrial activities, and growth in the human population. The world's volume of solid waste produced is gradually increasing; inadequate recycling and improper disposal of solid waste is a source of water, land and air contamination, and presents risks to human health and the atmosphere. Currently, policy in all countries is working on innovative approaches to tackling the problems posed by solid waste management (SWM). Various methods have been developed and utilized for effective solid waste disposal and segregation. Through an inductive proximity sensor and ultrasonic proximity sensor, this paper aims to separate tin can from the plastic bottle. Ultrasonic proximity sensor transmits ultrasonic waves to sense target presence or absence. This is connected to the inductive proximity sensor which is connected to a microcontroller to separate metals from plastics to process the data of each object. The device includes an inductive proximity sensor that is used to detect metallic objects without any contact. When the object reaches the sensor, the current flow of induction decreases, particularly on metals, as it has higher frequencies than plastic. The study was conducted with a total evaluation accuracy of 94%.
