- INTRODUCTION
In this modern era, A Smart City is not only a dream but also a reality. Because of a comfortable lifestyle, digital security and maintaining systems save time in urban life. So that we have developed an IoT-based Smart polluted water level detection for the drainage system with an easy monitoring method. We are mainly developing this project for large City-corporations where they have a low workforce and a low city development budget. This model is more efficient and effective than other maintenance tools. Arduino UNO is used to construct the device. For the data transfer system, we collaborated with this device between a Wi-Fi module and a city Wi-Fi hybrid protocol system. In this study, our main novelty has given below such as:
• IoT-based smart polluted overload drainage detection and transfer this data into the monitoring center.
• Low cost and long-lasting device develop for the alert and detection system.
• Designed a hybrid model having remote data access capability.
• Ensuring the accuracy perfection of this setup system.
If a city corporation set-up this device, they can reduce 30-40% of their extra monitoring fund . There is no necessity for any extra manpower to recruit. This device is cheaper and made with the latest technology. Remote data access is an efficient way to save time, so we apply this module . The Internet of things (IoT) is a new technique in this era and we can use it for better life and empowerment.
2. SYSTEM ARCHITECTURE AND MODEL
A. Proposed Model
Fig. 2 shows where to set up this monitoring device, where to send or execute its output signal and how they are
interconnected with sensors, Ethernet shield, city Wi-Fi and monitoring center.

For the data transferred to the database, a connection between the city Wi-Fi line with an IP address and Ethernet
shield took place. In the city database server station, access all data which is collected from the sensor. Lastly, this data
server transfers it into the city monitoring center.
B. System Architecture
In this system, Arduino UNO has worked as a central processing unit and Arduino Ethernet Shield [9] has used to
send classified data to the server database of city corporations. In Fig. 3, we are using Sensors to collect data
from nature. We are using an Ultrasonic Waterproof Range Finder Sensor (JSN-SR04T-2.0), which can measure 20 to
600 cm. As this system is waterproof, it would be sustainable for this project(A). The sensor will collect data
like the water level [10] in drainage as well as the distance between critical points. It will send data to Arduino UNO/microcontroller (MCU) to analyze whether it is hazardous or not. Arduino UNO is a microcontroller board
using ATmega328 AVR microcontroller with 20 digital inputs and outputs (B). Arduino UNO will work as a central
processing unit (CPU) and it will decide when the water level is at the dangerous point as it programmed.
Fig. 3. System Architecture with Activity process
When the water in drainage is in critical points, Arduino UNO will read data from sensors. After analyzing Arduino
Uno will send a signal to both Arduino Ethernet shield and Buzzer. The buzzer will be ranged as an emergency alarm
which will help municipality/city corporation workers to identify the critical points easily(C). With the help of a WIFI
connection, Arduino Ethernet Shield will inform the server room of the municipality. We used W5200 Arduino Ethernet
Shield, which is operated with 3.3 volts to 5 volts with 32kb buffer memory (D). Using this system, the authority
/municipality [11] will monitor the real-time condition of each point of the drainage system as a webpage. Authority
could take necessary steps by analyzing real-time data. By taking care of identified critical issues, the total drainage
system will work properly. This system is better than an analogue system and could reduce municipality
cleaner/worker, which is economically helpful.
3 TEST AND RESULT
Firstly, we have made a prototype to get the measure of how we will set out our complete system, it is required to do
relevant studies and build out as shown in Fig. 4.

This model is basically a smart development-based research project. We test for the final setup statement and it
works appropriately within 90-95% correct and gives good accuracy. We got this accuracy from Arduino testing and real-time web server testing. Rest percentage of accuracy cannot be secured due to heavy gaseous elements in the air. Better internet activity and setup will work better than our testing period. For its better working capability, any city corporation can easily use it and provide better service to the citizens.
