Design and implementation of home security system using PZT

Security is a major concern in our day-to-day life since it can prevent intentional or unintentional interference in human life with the proper operation of security system. In this project based research work, two set of piezoelectric transducer (PZT) are used. When anybody stands on PZT (I), the buzzer indicates the problem detection and LED light shows the problem occurring place. The buzzer and LED are centralized in a map so that one can monitor a large area with this system design. Microcontroller is used for continuous supply and PZT (II) is used to charge the battery. Piezoelectric transducer of high sensitivity must be selected in the system as security system detector to sense the failure of security within the shortest period of time. This system is best suitable for corporate offices, ATMs and home security.
