Password protected secured area

Description

The password-based security system is the device that has been developed to enhance the security of a place concerned where the entry of unauthorized individuals is restricted. The device works with the help of a microcontroller that has been set in such a way so as to respond to a certain binary code only. When the authorized user types a certain password with the help of a keypad the microcontroller checks it with the code it is supposed to compare with.

In the kit password-protected secured area if the entered code is correct it sends the signal to the gate to open, if the entered code is wrong then it would activate the theft alarm. This device is helpful in factories and laboratories where there are security concerns. It would help in protecting the stored material from unauthorized misuse or from being stolen.

In the kit password-protected secured area our interface is an advanced design of the interface in which the user can open the gate by entering his assigned correct password. The user can change his password also. The system supports multiple users and each user has its unique password. There is a switch matrix interfaced with the controller. When a particular sequence is pressed then the microcontroller decodes it allows the door to be opened through the motor driver and motor. If the sequence is pressed wrong then the buzzer will blow to give a siren. The password-protected secured system supports multiple users and the user can change its password after being verified. The system can be powered up by a 12V AC/DC power supply with a minimum of 1A of current.
