This document proposes an IoT-based smart city waste management system using ultrasonic sensors, a microcontroller, WiFi modem, and android app. The system monitors garbage bin levels, alerts when bins are full, and displays status on a web page. This allows for more efficient waste collection, reduced costs, and improved public services. The system implementation details include hardware components, software specifications, circuit diagram, and programming of the microcontroller to interface with sensors and transmit data via WiFi modem. Future work could expand monitoring to more bins across the city.

3. Objective
• To keep the city clean
• Continuous monitoring on garbage bin
• Reduce the cost and time on waste collection
• Improve the service of garbage collection
• Status of garbage bins shows on internet and android ap
p
• Public can complaint if delay on waste collection through
app.

4. Introduction
• In today's world a lot of waste is produced in a residential as well as in in industrial
environment. To dispose off these waste materials is also a big overhead to the o
nlookers and the authorities. If not disposed off timely they result into unhygienic c
onditions in the surroundings and may result into hazardous epidemics.Thus there
is a need to constantly monitor the garbage levels in the garbage bins.
• This project aims to solve this problem by using the modern technology put at its b
est. Alerting using the android application and IOT technology has been demonstr
ated in this project.

11. Working
• This project IOT Garbage Monitoring system is a very innovative system which will hel
p to keep the cities clean. This system monitors the garbage bins and informs about th
e level of garbage collected in the garbage bins via a web page. For this the system u
ses ultrasonic sensors placed over the bins to detect the garbage level and compare it
with the garbage bins depth. The system makes use of AVR family microcontroller, LC
D screen, Wifi modem for sending data and a buzzer. The system is powered by a 12
V transformer. The LCD screen is used to display the status of the level of garbage col
lected in the bins. Whereas a web page is built to show the status to the user monitori
ng it. The web page gives a graphical view of the garbage bins and highlights the garb
age collected in color in order to show the level of garbage collected. The LCD screen
shows the status of the garbage level. The system puts on the buzzer when the level o
f garbage collected crosses the set limit. Thus this system helps to keep the city clean
by informing about the garbage levels of the bins by providing graphical image of the b
ins via a web page.
