Abstract: A system and apparatus for monitoring physical phenomena and changes in structures which includes a plurality of programmable intelligent transducers arranged in an array, each of which is uniquely addressable by a remote controller to perform its intended measurement functions, translate the analog measurement obtained into digital signals and transmit same to the controller. The monitoring is selective to each individual intelligent transducer. The intelligent transducers combine measurement functions, microprocessor functions and communication functions all programmed and activated from this central controller.
