Smart Waste Bin Using Arduino

INTRODUCTION
1.1 BACKGROUND OF THE STUDY
WASTE is generated every day, from domestic, industrial, commercial and institutional establishments such as hospitals, market just to mention a few [4]. Solid waste management, monitoring and disposal are very important issues for most countries. Efficient waste management and disposal is required to maintain safe and green environment [5]-[6]. As a result, this necessitates the need for waste bins with lids to contain unpleasant sights and odors and to minimize contamination.
Dustbins (or Garbage bins, Trash Cans, whatever you call them) are small plastic (or metal) containers that are used to store trash (or waste) on a temporary basis. They are often used in homes, offices, streets, parks etc. to collect the waste.
In some places, littering is a serious offence and hence Public Waste Containers are the only way to dispose small waste.
Usually, it is a common practice to use separate bins for collecting wet or dry, recyclable or non-recyclable waste.
In this project, I have designed a simple system called Smart Dustbin using Arduino, Ultrasonic Sensor and Servo Motor, where the lid of the dustbin will automatically open itself upon detection of human hand.

1.2 PROBLEM STATEMENT
Environmental waste causes serious sickness and diseases to people living in such environment. Waste bin contains microorganism which can affect human health and when the lid is left open cal as well cause air pollution which is also dangerous to human health. It solves the problem of waste collection and keeping. This device opens the lid of the dustbin automatically upon detection of human hand and closes after the waste is dropped.

1.3 AIM OF THE PROJECT
The main of this work is to build a device that makes it possible to collect and store waste without making contact with the waste bin.
1.4 SCOPE OF THE PROJECT
Smart dustbin was built using ARDUINO UNO, ultrasonic sensor which will sense the item to be thrown in the dustbin and open the lid with the help of the motor. It is an IOT based project that will bring a new and smart way of cleanliness. It is a decent gadget to make your home clean, due to practically all offspring of home consistently make it grimy and spread litter to a great extent by electronics, rappers and various other things. Since the smart dustbin is additionally intriguing and children make fun with it so it will help to maintain cleanliness in home. It will be applied for various type of waste. Dustbin will open its lid when someone/object is near at some range then it will wait for given time period than it will close automatically. Here lid will close when you don’t want to use and it will only open when it required.

1.5 SIGNIFICANCE OF THE PROJECT
This device helps in maintaining the environment clean with the help of technology. It is a sensor based dustbin so it would be easy to access/use for any age group.

1.6 PURPOSE OF THE STUDY
The main purpose of this work is protect our environment from Air pollution due to a dustbin and also human being from contacting bacteria and virus which can produce life harmful diseases for human.

1.7 ADVANTAGES OF THE PROJECT

Following are the advantages of using Smart dustbin:
• A reduction in the number of waste collections needed by up to 80%, resulting in less manpower, emissions, fuel use and traffic congestion.
• A reduction in the number of waste bins needed.
• Maintain environment hygiene (i.e. no overflowing of waste and less unpleasant odor).
• It will help in bringing evolution by technology in term of cleanliness.

1.8 PROJECT ORGANISATION
The work is organized as follows: chapter one discuses the introductory part of the work, chapter two presents the literature review of the study, chapter three describes the methods applied, chapter four discusses the results of the work, chapter five summarizes the research outcomes and the recommendations.
