Security and monitoring system by using RFID tags and multiple sensors

The goal of this project is to perceive and detect gas leakage, gas cylinder drop level, food count and library book history of the student by using gas sensor, weight sensor and RFID (Radio Frequency Identification) approach and to provide complete information and usefulness needed. This proposed system defines the design of RASPBERRY PI based on a security system for use in industries or hostel. Industries have been a key part in the swelling of the nation's economy. The swelling in industries has also lead to the swelling of tragedies in the past decades, out of which majority caused by omission or human errors. The initiate method is discussed a menace board system to detect perilous gas leaks, Gas cylinder drop level, hostel food count and library book count from the set value using raspberry pi, gas sensor, weight sensor and RFID reader. A congruous measure is taken by the raspberry pi system turns on and makes a message send to the security van through GSM modem. The alert notification sends to the cell phone, with respect to the situation to minimize the menace.
