Abstract
A method of obtaining data about a structure includes providing a plurality of sensor modules on the structure. Each of the sensor modules includes a sensor, a processor, a sensor module precision timekeeper, and a sensor module transceiver. One of the plurality of sensor modules includes an energy harvesting device. The processor and the sensor module transceiver of this one of the plurality of sensor modules are powered solely with electricity derived from the energy harvesting device. The method further includes providing a base station. The method further includes periodically wirelessly receiving a broadcast resynchronization timing packet with each of the sensor module transceivers, wherein the broadcast resynchronization timing packet received by each of the sensor module transceivers includes a common resynchronization time value. The method further includes periodically resynchronizing each of the sensor module precision timekeepers based on a signal derived from the resynchronization time value. The method further includes digital sampling of the sensor module sensor in each of the sensor modules to provide digital sensor data, and providing a time stamp to the digital sensor data wherein time in the time stamp is provided by the sensor module precision timekeeper. The method further includes wirelessly transmitting data from each of the plurality of sensor modules to the base station, wherein the data is derived from the time stamped digital sensor data. The method further includes receiving and aggregating the data from each of the plurality of sensor modules in the base station.
