Development of Automated Room Security System.pdf

The work on “Development of automated room security system” using Microcontroller is a reliable circuit that takes over the task of security of a room very accurately. When somebody enters into the room then the count will be incremented by one and the set limit is checked, if the count is less than the set limit then the door opens and the person is granted access. When any one leaves the room then count will be decremented by one. If the total count exceeds the set limit then the buzzer is sound and the image of the person trying to enter the room is captured via a camera. The microcontroller does the above job. It receives the signals from the sensors, and this signal is operated under the control of software which is stored in ROM. 89s51Microcontroller continuously monitor the sensors, an IR Sensor sends signal to the microcontroller , to increment or decrement the count accordingly. The system includes IR sensor, microcontroller, LCD, display, buzzer, camera and a 12v power is supplied to run the system. The system uses a compact circuitry built around 89s51 microcontroller programs are developed in Embedded C.
