3. INTRODUCTION :-
• This security is a prime concern in our today’s life.
• Our project aims at a system that provides the required
authority, the ability to change the password as and when
needed.
• Organizational security is an important factor these days.
• With this system we can easily control the security system.
• We can easily use it in our home,garage,office etc.
• Hence, provide “AUTOMATION” & “SECURITY”.

4. HARDWARE REQUIREMENTS :-
8051 series Microcontroller
Bluetooth Device
EEPROM
Capacitors
Cables and Connectors
PCB and Breadboards
Switch
Resistors
IC Sockets
Diodes
Voltage Regulator
Transformer
LCD

13. Application :-
 This simple circuit can be used at residential places to ensure
better safety.
 It can be used at organization to ensure authorized access to
highly secured places.
 With a slight modification this project can be used to control
the switching of a loads through password.

14. ADVANTAGES :-
• Simple installation.
• Provide ease and automation.
• Since, it is the system having password facility,
provide security as well.

15. Conclusion:
It creates an advanced system which gets rid of the
problems in the existing system while keeping the costs
low. This system involves bluetooth technology. This
bluetooth device is connected to the microcontroller .This
project also involves android application. Android
application send data through bluetooth .Pairing is done
between the android device and the microcontroller and
Controlled Remote Password Security .
