ABSTRACT
Structural Health Monitoring is an emerging field of
science and technology. The process of implementing
a damage detection and characterization strategy for
engineering structures is referred to as Structural
Health Monitoring (SHM). The SHM process
involves the observation of a system over time using
periodically sampled dynamic response measurements
from an array of sensors, the extraction of damage
sensitive features from these measurements, and the
statistical analysis of these features to determine the
current state of system health. The research paper
describes the piezo-vibrational sensor and
accelerometer sensors to monitor the prototype of
bridge.
Keyword: Sensor, SHM.
I. INTRODUCTION
The process of implementing a damage detection and
characterization strategy for engineering structures is
referred to as Structural Health Monitoring
Here damage is defined as changes to the material
and/or geometric properties of a structural system,
including changes to the boundary conditions and
system connectivity, which adversely affect the
system's performance. The SHM process involves the
observation of a system over time using periodically
sampled dynamic response measurements from an
array of sensors, the extraction of damage
features from these measurements, and the statistical
analysis of these features to determine the current
state of system health. For long term SHM, the output
of this process is periodically updated information
regarding the ability of the structure to perform its
intended function in light of the inevitable aging and
degradation resulting from operational environments.
After extreme events, such as earthquakes or blast
loading, SHM is used for rapid condition screening
and aims to provide real time, reliable information

should understand how the health of structure like
buildings, bridges or any other civil structure is
related and monitored by Electronics &
communication. The health of a structure is related
and monitored in the similar fashion as the health of a
human being is monitored by health monitoring
devices and systems like Electronic blood pressure
machine, Blood sugar checking device,
Cardiovascular monitoring systems, ECGs, Activity
monitoring systems etc. All these devices work by
collecting the data from human body in the form of
signals through electronic sensors and then converting
into the electric signal. This data is stored processed
and calibrated to any aspect of human health. This
value is then compared to a set reference value and
checked whether it is higher or lower or equal to it.
Accordingly the health of a human body is monitored.
Now in the similar fashion the health of a structure is
monitored by Structural Health Monitoring Systems.
II. Problem Definition
Bridges are defined as structures which provide a
passage over a gap without blocking the passage
beneath. It can be defined as the structure providing
passage over an obstacle without closing the way
beneath. The required passage can
road, a railway, pedestrian, or a canal. The paper
focus on the technologies to be implemented to
minimize the failures after construction.
III. Objective
The basic objective is to find the basic cause of the
failure of the bridges. The study is conducted to help
analyze why bridges fail. What signs should be
observed when a bridge is about to fail and what
possible actions must be taken to either prevent or
reduce the chances of the failure. Wireless sensor

network technique is used to help the detection of the
movement of the girders.
IV. Methodology
The methodology starts with the investigation of the
previous work and survey of research papers. My
approach is based on microcontroller programming
based on Arduino, which is an open source platform,
thus making it more interactive and user friendly.
With Arduino, we can build objects that can respond
to and/or control light, sound, touch, and movement.
Arduino has been used to create an amazing variety of
things, including musical instruments, robots, light
sculptures, games, interactive furniture, and even
interactive clothing. The sensors used are Piezo
Vibration Sensor and Accelerometer (ADXL335). For
online data logging Blynk app will be deployed.
Blynk was designed for the Internet of Things. It can
control hardware remotely, display sensor data, can
store data, visualize it and do many other cool things.
V. Results
The concept mainly consists of three parts Bridge
prototype, Transmitter Module and Receiver Module.

There are three major components in the platform:
Blynk App - allows us to create amazing
interfaces for your projects using various widgets
we provide.
Blynk Server - responsible for all the
communications between the Smartphone and
hardware. We can use our Blynk Cloud or run
private Blynk server locally. It is open
could easily handle thousands of devices and can
even be launched on a Raspberry Pi.
Blynk Libraries - for all the popular hardware
platforms - enable communication with the server
and process all the incoming and out coming
commands.
Every time we press a Button in the Blynk app,
the message travels to the Blynk Cloud, where it
magically finds its way to our hardware. It works
the same in the opposite direction and everything
happens in a Blynk of an eye.

The fact of getting the information about various
parameters of the health of a building on our mobile
phone is very useful and handy. A weak structure is a
threat to human life and property too. This paper
provides the information about the various
components used and the programming done using
Arduino. Even structures have life and we (engineers)
are here to protect it from various diseases.
