    Security is a prime concern in our day-today life. Everyone wants to be as much secure as possible. An access control for doors forms a vital link in a security chain. The Microcontroller based Home Security System can be adopted at Home it has various type of Sensors. In our Project we have magnetic sensors, Wire Loop sensors, Fire sensors. The system is fully controlled by the 8 bit microcontroller AT89C52 which has a 8Kbytes of ROM for the program memory.
    The Microcontroller will continuously monitors all the Sensors and if it found any security problem then the Microcontroller will switch on the Alarm until the Reset button was Pressed.

    Sir,

    Could you please let me know whether the led's correspond to the input will flash until the reset button pressed? I mean the input returned to the normal condition after a few seconds, still the led will be on?

    If I want to increase the inputs up to 10 and the outputs also to 10 then what changes we need to make in the code?

    :)

    No, the LED will be switched on when a fault occurs. But you can change as your wish. The code should be changed.

    For monitoring 10inputs, you can connect the inputs to the port which are free. The program should also be changed. [8D]
