Design of a Bank Vault Security System with Password, Thermal & Physical Interrupt Alarm

Security is one of the most concerning factor in bank vault system. Without proper and strong security a vault can be penetrated. Most of the systems are based on human supportive security protocol. The main purpose of this paper is to construct a microcontroller based automated system which can give instant protection against any break-in by hackers or against physical penetration and send warning signal to the law enforcement team immediately. The system consists of a microcontroller associated with passive infrared sensor, shock sensor and keypad with display panel.
