Smart Dustbin With Iot and Hierarchical Waste Segregation

Abstract

Managing waste efficiently requires more than simply providing additional disposal containers [1]. Waste is often mixed at the point of disposal, and bins may remain unchecked until they become full [3]. This research work presents a Smart Dustbin with IoT and Hierarchical Waste Segregation that combines waste classification, automatic segregation, fill-level monitoring, and remote notification in a single prototype [7]. The system uses an Arduino Uno as the main controller. A metal sensor is checked first to identify metallic waste. For non-metallic material, a moisture sensor is then used to distinguish wet waste from dry waste. According to this decision sequence, a motor-driven mechanism directs the material to the corresponding wet, dry, or metallic compartment. An ultrasonic sensor is used separately to monitor the fill level, while the IoT module sends the bin status to a remote monitoring platform and provides an alert when the configured capacity limit is reached [2]. The research work focuses on a simple sensor-based approach that can reduce manual segregation and make bin monitoring more convenient [10]. The prototype is intended as a practical and low-cost solution for educational institutions, offices, residential areas, and other shared environments.
