Structural health monitoring system using WSN for bridges

Nowadays, a natural disaster is happening mostly on the earth. For examples flood, earthquake etc. These types of disasters like flood, earthquake can cause loss of property damage or life, so the structural health monitoring system is best solution for these types of problems. Structural health monitoring system is used to measuring the key parameter of the structural and environmental conditions on a continuous base at real-time. Purpose of SHM are detect structure damage, safety, disaster mitigation etc. Wireless sensors to monitor physical or environmental condition like pressure, level of water, acceleration etc. For bridges and dams application, wireless sensor measures the acceleration, tilting angle of bridge pillar and water level. The wireless sensor network is used in industry, urban terrain tracking and civil structure monitoring, security and surveillance, smart buildings etc. The wireless sensor network is consisting of number of nodes and one or more base stations. The sensor nodes in a sensor network are capable of collecting bridge or dam information and communicate with other connected nodes in the network. It is also capable of performing some processing part. Wireless sensor nodes are consisting microcontroller, transceiver, power management unit (power source), and one or more sensors. For bridge application we have used accelerometer sensors and ultrasonic sensor. The main aim of this project is to minimize the structural damages and prevent the life and property.
