A sensor for a system adapted to monitor the structural integrity of a building enters a power conserving sleep mode in which the supply of power is inhibited to nonessential functions, including sensing functions and radio functions. A real time clock on the sensor preferably prompts periodic wake up of the sensor from sleep mode, at which time the supply of power to the sensing functions and radio functions is resumed if indicated to perform monitoring and reporting of structural integrity information.
