Abstract:
This project system uses wireless network on real time basis for bridge health monitoring purpose. It can transmit the data continuously for several minutes. In that detection of ‘vibrations’, ‘crack’ & ‘sand level at the base’ occurred . Currently Bridge Inspection is done by manually each time and also takes lots of time to find & detect any fault. It requires specialized or experienced man for inspection of bridge. They have to monitor the condition of bridge by visual inspection thoroughly.Conventionally, a technician is responsible to detect and measure cracks in the field.Then implementing the correction process for any crack, sand level of the bridge is difficult. Also the more attention required at the time of rainy season. In order to test the proposed methodology in this paper, several experiments were conducted in a controlled environment and their results were compared with other methods. In addition, experiments with real structures were conducted. Our proposed project research is focussing of implementation of system having sensors, Zigbee technique which informs bridge condition to nearby officers. This advance technique using zigbee is very helpful to human And nation also.

Hardware:
➢ Microcontroller
Microcontroller is a compressed micro computer manufactured to control the functions of embedded systems in office machines, robots, home appliances, motor vehicles, and a number of other gadgets. A microcontroller is comprises components like - memory, peripherals and most importantly a processor.
➢ LEDS
In the simplest terms, a light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is produced when the particles that carry the current (known as electrons and holes) combine together within the semiconductor material
➢ ADXL335
The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±3 g. ... The user selects the bandwidth of the accelerometer using the CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins.
➢ ULTRASONIC SENSOR
An ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves. An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object's proximity
➢ LCD - 16 x 2
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. The 16 x 2 intelligent alphanumeric dot matrix display is capable of displaying 224 different characters and symbols. This LCD has two registers, namely, Command and Data.
➢ ZIGBEE transiever
Zigbee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power wireless IoT networks. ... The protocol allows devices to communicate in a variety of network topologies and can have battery life lasting several years.
➢ Power supply circuit
A power supply is an electrical device that supplies electric power to an electrical load. ... The input and output are usually hardwired circuit connections, though some power supplies employ wireless energy transfer to power their loads without wired connections.
Software:
➢ Embedded c
Embedded C is a generic term given to a programming language written in C, which is associated with a particular hardware architecture. Embedded C is an extension to the C language with some additional header files. These header files may change from controller to controller. The microcontroller 8051 #include<reg51
➢
The Arduino Integrated Development Environment (IDE) is a cross-platform application (for Windows, macOS, Linux) that is written in functions from C and C++. It is used to write and upload programs to Arduino compatible boards, but also, with the help of third-party cores, other vendor development boards
