This document describes an IOT-based garbage monitoring system that uses ultrasonic sensors attached inside dustbins to detect whether they are empty or full. The sensor data is sent to an ATmega16 microcontroller via WiFi, and the microcontroller displays the status on an LCD and sends the data to a server. The server software manages the live dustbin level monitoring data. The system is intended to help manage waste more efficiently in places like homes, offices, and colleges.

2. Objective
The objective of the system is to design and develop IOT
based garbage monitoring system. In this system ultra
sonic sensor is attached inside the dustbins to measure
the status of dustbins whether it is empty or full.
This data is send to the server using IOT link.

3. Introduction
The system deals with an innovative idea to develop IOT based
garbage monitoring system.
In this system ultra sounds sensor is attached inside the
dustbins to measure the status of dust beans whether it is
empty or full.
All the dustbins data will be send to the atmega16
microcontroller. The microcontroller will display the status of
dustbin on LCD display. And send every dustbin data to the
server using IOT link.
The server computer has software running on it based on .NET.
Server will manage all received data for the live monitoring.

4. Literature survey
 Nowadays, there are tons of flats and apartments which have been built in
the rapid urbanization area. This is due to high housing demands which
have been drastically risen as a result of migration from villages to cities to
find works. In order to accommodate the growing population in the urban
area, the government has built flats, apartments or condominiums, to
provide shelter for them. Besides, flats become popular mainly in the
United State, Europe and other developing countries.
 There are several issues faced by the inhabitants of the flats. One of them
is the issue of the domestic solid waste disposal, which cause pollutions.
Unlike landed houses, the flats’ waste disposal bins are shared among all
residents which live in the same building, and thus, the bins tend to be
filled very quickly. Thus, an unsystematic and inefficient disposal waste
management may cause the bins to be always full with of garbage, and
further littering from the residents will cause the garbage piles to be
scattered outside the bins. Therefore, there will be a question of sanitary
as those garbage piles may become the root cause of illness and diseases
like dengue, diarrhea, and cholera.

attendance and calculate the % of current attendance.
If attendance is low then it will automatically send a email
to his family members.
It can also send a important notice to students mail box.

8. Hardware Used:
ATmega16 Microcontroller
LCD display
WI-FI module
Ultrasonic Sensor Module HC-SR04
Server computer

9.  When we have to learn about a new
computer we have to familiarize about the
machine capability we are using, and we can
do it by studying the internal hardware design
(devices architecture), and also to know
about the size, number and the size of the
registers.
 A microcontroller is a single chip that
contains the processor (the CPU), non-volatile
memory for the program (ROM or flash),
volatile memory for input and output (RAM),
a clock and an I/O control unit. Also called a
"computer on a chip," billions of
microcontroller units (MCUs) are embedded
each year in a myriad of products from toys to
appliances to automobiles. For example, a
single vehicle can use 70 or more
microcontrollers. The following picture
describes a general block diagram of
microcontroller.

10. Wi-Fi Module - ESP8266
 The ESP8266 Wi-Fi Module is a self contained SOC
with integrated TCP/IP protocol stack that can give any
microcontroller access to your Wi-Fi network. The
ESP8266 is capable of either hosting an application or
offloading all Wi-Fi networking functions from another
application processor. Each ESP8266 module comes
pre-programmed with an AT command set firmware,
meaning, you can simply hook this up to your Arguing
device and get about as much Wi-Fi-ability as a Wi-Fi
Shield offers (and that’s just out of the box)! The
ESP8266 module is an extremely cost effective board
with a huge, and ever growing, community.
 This module has a powerful enough on-board
processing and storage capability that allows it to be
integrated with the sensors and other application
specific devices through its GPIOs with minimal
development up-front and minimal loading during
runtime. Its high degree of on-chip integration allows
for minimal external circuitry, including the front-end
module, is designed to occupy minimal PCB area. The
ESP8266 supports APSD for VoIP applications and
Bluetooth co-existence interfaces; it contains a self-
calibrated RF allowing it to work under all operating
conditions, and requires no external RF parts.

11. 16X2 LCD Display
 LCD (Liquid Crystal Display) screen is an electronic
display module and find a wide range of applications.
A 16x2 LCD display is very basic module and is very
commonly used in various devices and circuits. These
modules are preferred over seven segments and
other multi segment LEDs. The reasons being: LCDs
are economical; easily programmable; have no
limitation of displaying special & even custom
characters (unlike in seven segments), animations
and so on.
 A 16x2 LCD means it can display 16 characters per
line and there are 2 such lines. In this LCD each
character is displayed in 5x7 pixel matrix. This LCD
has two registers, namely, Command and Data.
 The command register stores the command
instructions given to the LCD. A command is an
instruction given to LCD to do a predefined task like
initializing it, clearing its screen, setting the cursor
position, controlling display etc. The data register
stores the data to be displayed on the LCD. The data
is the ASCII value of the character to be displayed on
the LCD. Click to learn more about internal structure
of a LCD.
