Mini Project for course Energy Management for IoT Devices

Internet of Things (IoT)C++MIT

Abstract

Smart Dustbin is an open-source Internet of Things (IoT) project. Mini Project for course Energy Management for IoT Devices. The Smart Dustbin is designed to streamline the waste disposal process, making it hands-free and intelligent. It's perfectly suited for busy public spaces, reducing the need to touch waste bins and promoting efficient waste sorting and recycling. It is built using C++. Key capabilities include: Automatic Lid Opening : Opens the lid automatically as someone approaches, using an ultrasonic sensor; Waste Segregation : Separates waste into biodegradable, hazardous, and non-biodegradable categories via voice commands; Fill Level Monitoring : Uses sensors to monitor how full the bin is and alerts when it's time to be emptied. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

The Smart Dustbin is designed to streamline the waste disposal process, making it hands-free and intelligent. It's perfectly suited for busy public spaces, reducing the need to touch waste bins and promoting efficient waste sorting and recycling.

The Smart Dustbin project is a cutting-edge waste management solution that leverages advanced technology to automate waste disposal, enhance environmental sustainability, and ensure hygiene. Developed at the SRM Institute of Science and Technology, this innovative system utilizes a combination of sensors, microcontrollers, IoT connectivity, and voice recognition to provide a smarter waste management solution on campus.

2. Objective

Mini Project for course Energy Management for IoT Devices

This project demonstrates how C++ can be applied to a real-world Internet of Things (IoT) problem.

3. Key Features / Modules

  • Automatic Lid Opening : Opens the lid automatically as someone approaches, using an ultrasonic sensor.
  • Waste Segregation : Separates waste into biodegradable, hazardous, and non-biodegradable categories via voice commands.
  • Fill Level Monitoring : Uses sensors to monitor how full the bin is and alerts when it's time to be emptied.
  • Voice Command Recognition : Allows for hands-free operation with simple voice commands.
  • Solar-Powered : Utilizes solar panels for an eco-friendly power source.
  • IoT Connectivity : Integrates with Blynk for remote monitoring and user notifications.
