Multi Sensor Approach in Structural Health Monitoring of Buildings

Structural Monitoring of buildings has a notable impact to the safety of the population. By continuously monitoring the health of the structure we may reduce the risk factor of facing the damage and provide safety for the population. Structural health monitoring is effectively carried out by placing multiple sensors for acquiring timely information. The main objective is to develop a structural monitoring and indication system based on wireless sensor network (WSN). The system continuously monitors the acceleration, vibration and the overload experienced by the building and indicates the concerned authority in case of severe damage. Furthermore, it has fire and gas alarm function which will set ‘OFF’ the power supply within the building. Using PIC16F877A, NRF24L01, GSM, the wireless communication between the nodes and PC monitoring is carried out which implements the control. This will help the maintenance and safety of the building. The system will be simulated and tested for its capabilities.
