Abstract
The objective of this project is to develop a wireless sensor node for the SmartBrick platform, which provides a low-cost and autonomous method for structural health monitoring. The SmartBrick sensor node leverages the Zigbee short-range communication capabilities of the base station to increase the monitoring range. The primary function of the node is to interface to humidity, temperature, tilt, strain, and vibration sensors and transmit their values to the base station via Zigbee. Long-range communication of data and alerts will be through the base station, which serves as the gateway to the outside world, and relays remote configuration and maintenance commands to the sensor nodes.
One of the primary motivations behind development of the sensor node is high-resolution monitoring of strain. Each wireless sensor node will be able to measure strain from 16 different locations on a structure, by multiplexing these gauges to the same signal conditioning circuit, which drastically reduces the number of nodes required for monitoring an area. Data collection can take place at regular intervals, or when triggered by events of interest. Each sensor node includes sufficient memory to store a day’s data, although the system default is to transmit the collected data to the base station once per hour.
