• Bridges are critical elements of transportation infrastructure, serving as vital links for the
movement of people and goods. To enhance the safety and resilience of bridges, this
report presents the concept of a smart bridge monitoring system that leverages advanced
technologies. The proposed system incorporates the use of the GSM900 network, Arduino
Uno microcontroller, water level sensors, an LCD display, jumper wires, sun board housing,
and two servo motors for controlled operations. This system's primary purpose is to
continuously monitor water levels around the bridge, providing early warnings and enabling
automated control of bridge elements to ensure the safety of both infrastructure and the
public.

5. 1.INTRODUCTION
• Bridges are fundamental components of any transportation network, providing critical connections over bodies of water,
ravines, and challenging terrain. Ensuring the safety and functionality of bridges is paramount for public safety and the
efficient operation of transportation systems. While bridges are designed to withstand various environmental challenges,
they can still be susceptible to damage from natural disasters, particularly flooding.
• In this report, we introduce a concept for a Smart Bridge Monitoring System, which utilizes a combination of electronic
components, including the GSM900 network, Arduino Uno microcontroller, water level sensors, an LCD display, jumper
wires, sun board housing, and two servo motors. This system is designed to continuously monitor water levels around the
bridge, collect data, and provide early warnings in the event of rising water levels, which could potentially pose a threat to
the bridge's structural integrity or the safety of people using it.

6. 2. Components Used
• 2.1. GSM900 Module
The GSM900 module serves as the communication backbone of the smart bridge monitoring system. It enables wireless
data transmission and reception, facilitating real-time monitoring and communication between the bridge's monitoring
system and a central server or control station. This communication is crucial for timely responses and remote control.
• 2.2. Arduino Uno
The Arduino Uno microcontroller is the central processing unit of the system. It is responsible for data acquisition,
processing, decision-making, and control of other components. The Arduino Uno is programmed to interface with various
sensors, collect data, analyze it, and trigger responses as necessary.

7. • 2.3. Water Level Sensor
Water level sensors are strategically placed around the bridge's vicinity to continuously measure the water levels in adjacent
bodies of water, such as rivers, streams, or reservoirs. These sensors employ various technologies, such as ultrasonic or
float-type sensors, to provide accurate and reliable data regarding water levels.
• 2.4. LCD Display
The LCD (Liquid Crystal Display) is an essential user interface component. It is employed for local monitoring and
debugging purposes. The LCD displays real-time data on water levels, system status, and any alerts, allowing maintenance
personnel or on-site engineers to quickly assess the situation

8. • 2.5. Jumper Wires
Jumper wires play a crucial role in the system by establishing electrical connections between various components. They
serve to maintain an organized and efficient wiring infrastructure, ensuring the seamless flow of data and control signals
throughout the system.
• 2.6. Sun Board
The sun board, made of durable and weather-resistant materials, serves as the housing for the smart bridge monitoring
system. Its primary function is to protect the electronic components from environmental elements such as rain, sunlight, and
dust. Additionally, the sun board is designed to be robust, ensuring the system's durability and longevity.

9. • 2.7. Servo Motors
Two servo motors are integrated into the system to enable controlled and automated actions on the bridge. These motors
can be used to manipulate specific bridge elements, such as barriers or gates, to regulate access. For instance, if rising
water levels pose a potential threat, the servo motors can be activated to close barriers and prevent vehicular or pedestrian
traffic.

10. 3. Working Principle
• 1.Water Level Sensing: Water level sensors, distributed at strategic points around the bridge, continuously monitor the
water levels in nearby bodies of water. These sensors are equipped with the ability to provide real-time data on water
levels.
• 2.Data Collection: The Arduino Uno, functioning as the central processing unit, collects data from the water level
sensors. This data is then processed to assess the risk of flooding or water-related damage. The Arduino Uno is
programmed with algorithms that analyze the collected data and determine whether the water levels present a potential
threat.

11. • 3.Control and Response: Based on the analysis data, the Arduino Uno is capable of triggering actions to control
specific bridge elements. This control is achieved through the integration of two servo motors. For example, if the system
determines that water levels have reached a critical point, the Arduino Uno can activate the servo motors to close barriers
or gates, restricting access to the bridge.
• 4.Communication via GSM900: The system uses the GSM900 module to communicate with a central monitoring system
or control station. Real-time data is transmitted, allowing external monitoring personnel to track the bridge's status and
receive alerts in case of emergency. The GSM900 module ensures that the system remains connected to the central
server, even in remote locations.

12. • 5.Local Monitoring: Local monitoring and debugging are possible through the LCD display. This display provides real-
time data on water levels, system status, and any control actions initiated by the Arduino Uno. It serves as a valuable tool
for on-site personnel to quickly assess the situation.
