Health monitoring of bridges is one of the important challenges in cities. Monitoring the damages in the bridge is an increasing concern for the benefit of public as there is a threat to people’s life and property. Instalment of wireless sensor network is one of the possible solutions to structural health monitoring. The ZigBee convention is utilized for observing the scaffolds harms and can screen different parameters, for example, temperature, weight, vibrations, stress and dampness. Stack cell, flex sensors and vibration sensors can be utilized to screen the condition. The heap cell is utilized to discover the limit of scaffold. The flex and vibration sensor is utilized to recognize the inward and outer harms .If harm is distinguished by means of ZigBee correspondence the harm location is educated to the Base Station. They locate an extensive variety of uses in natural checking, modern observing, and auxiliary checking
