ULTRA LOW POWER SMART WIRELESS SENSOR WITH EVENT BASED OPERATION
Wireless sensor networks have shown promising solution for large infrastructure monitoring because of their ease of installation and cost-effectiveness.Long-term Structural Health Monitoring however,is still a challenge since it is continuous monitoring and is expensive in terms of power consumption.Reducing the battery life of sensor node limits the efficiency of sensor network and increases the maintenance cost of system.To overcome this challenge,energy harvesting technique is introduced but still power management in sensor node is critically important.This study presents event based power efficient hardware which is designed to significantly improve the power efficiency of sensor node without compromising the network efficiency.The designed hardware is ultra-low power microcontroller based with programable event detection mechanism.Our proposed architecture can detect ambient response in structure when main sensor node is in deep sleep and wake up the network for monitoring.The framework of hardware is service-oriented that is extensible and reusable for different SHM application.
