Sensor and monitoring system

A method for monitoring integrity of a structure, the method comprising:

• collecting data from a plurality of sensor modules, the plurality of sensors positioned to monitor the integrity of a structure;
• time synchronizing at least a portion of the data from the plurality of sensor modules, the portion of the data including a plurality of measurements and an another plurality of measurements;
• periodically routing the portion of the data from the plurality of sensor modules to a gateway, the gateway being configured for bi-directional communication with the plurality of sensor modules;
• receiving the plurality of measurements to a communication module;
• the communication module exiting a standby state and transmitting the plurality of measurements to an offsite system without receiving a request from the offsite system to transmit the plurality of measurements;
• receiving the another plurality of measurements to the communication module;
• after transmitting the plurality of measurements, the communication module reentering the standby state until receiving the another plurality of measurements;
• and
• the communication module exiting the standby state and transmitting the another plurality of measurements without receiving a request from the offsite system to transmit the another plurality of measurements.
