Abstract

The iBin system is an innovative IoT-based waste management solution designed to address the growing need for efficient garbage disposal and monitoring. Using an ESP32 microcontroller, ultrasonic sensors, and a combination of moisture and infrared sensors, the dustbin automatically categorizes waste into wet and dry sections. A servo motor-driven lid mechanism ensures contactless operation, improving hygiene. The system logs real-time waste levels and sorting data to ThingSpeak, allowing owners to visualize trends and receive alerts when the dustbin reaches capacity. An OLED display provides immediate status feedback, while a buzzer signals threshold warnings locally. The integration of a custom mobile application allows users to track bin levels, historical data, and collection reminders remotely. By automating sorting and leveraging IoT cloud analytics, iBin enhances waste segregation, reduces human error, and ensures a cleaner and smarter environment.

Project Description

The primary objective of iBin is to automate the waste management process by designing a dustbin capable of sorting wet and dry garbage using sensors, while providing real-time monitoring and threshold alerts. The system leverages IoT technology to log waste data to a cloud server like ThingSpeak, enabling data visualization and analytics. A custom mobile application allows users and administrators to track waste levels remotely, ensuring timely waste collection and preventing overflow. Additionally, the system aims to enhance environmental sustainability by reducing human intervention in waste sorting and management, promoting efficient recycling and hygiene. By integrating microcontrollers, servo motors, sensors, and a motor driver, iBin provides a practical, scalable, and cost-effective solution for households, offices, and public places. Ultimately, the project seeks to improve cleanliness, reduce manual labor, and contribute towards a smart city initiative.
