Electric Field and Ultrasonic Sensor Based Security System

Abstract

This paper proposes an inexpensive solution towards the safe-keeping of the precious artifacts in museums, art galleries and private collections by employing an innovative non-contact based sensing mechanism clubbed with some of the previously used, well tested and efficient sensor-networks based on physical parameters. Such security standards are met by covertly deploying a low level electric field, with intent to perceive any intrusion by the trespasser for a visual or audio alert. Further, it explains how this system incorporates with other sensing devices such as ultrasonic sensors and the control units like micro controllers and processors to deliver a fail-safe security system.
