IoT based Waste Management for Smart Cities

Our country is facing vast challenges in the environment due to waste generation some of them were: inadequate waste collection, transport, treatment, and disposal. One of the important challenges is from its inception till its disposal. Our country can't cope with the current systems by an increasing urban population with the volumes of waste, and this result on the public and environmental health pollution. Unhygienic conditions are created due to the flooding of the dustbins each day. This paper is for the commenting of the challenges, barriers, and opportunities for the betterment of collection, and segregation in the field of waste management. When it senses the nearby trash the dustbin that function automatically, and it is built through a prototype. Dustbins are placed all over the city, and delivered with low cost embedded method to help in tracking of the garbage bins. The Blynk app indicates through SMS as soon as dustbin has reached its maximum level, to the unwanted management department. An immediate action would be taken by the alarmed authorities once the position of the bin is sent via the Internet. The proposed system is developed by using ultrasonic sensors, nodemcu, servo motor, Blynk app.

I. Introduction

Wired and wireless networks are used for connecting the surrounding without the user intervention is called Internet of Things (IoT). Information is exchanged between the objects. The level of water is measured using ultrasonic sensor inside a tank. It consists of transmitter and receiver. High frequency waves are emitted from the transmitter and it is received by the receiver. The ultrasonic sensor is controlled by the 32-bit microcontroller [1].
