A high sensitivity structural health monitoring network includes a plurality of sensor nodes disposed apart from each other and communicating through one or more sensor channels. The nodes include smart sensor circuit boards with an interface to a wireless smart sensor board platform, a multi-axis accelerometer having a measurement range and resolution set to provide sensitivity to measure ambient structural vibrations an analog to digital converter for converting signals that includes a plurality of individual channels being individually programmable for signal conditioning for providing data to the interface. A network framework provides network services including a time synchronization service with network-wide global timestamps for sensor data and a unified sensing service that supports collection of data for all sensor channels from all nodes together with a single set of associated time stamps.
