Low Cost Removable (Plug-In) Electronic Password - Based Door Lock
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 7
Abstract
Security has always been an important factor in life. We need our home and offices to be secure. In this paper the plug-in electronic door lock is designed to have two levels of security and it comprises two sections. The first section is mobile section which serves as the key. It contains a matrix keypad, LED, and a microcontroller; it can be carried around in the pocket while the second section, which is stationary, is installed at the door. When the mobile section is plugged into the static section, the two sections have a handshake; without the internal handshake between the two microcontrollers the static section will not accept the mobile section. If the correct password is entered the door lock will open the door for 15 seconds after which it will automatically close the door back. If the wrong password is entered three times, the system will keep the door locked, activate alarm and an SMS will be sent to the authorized personnel to stop the alarm and reset the system so that password can be entered again. This work can be used for access control in homes and offices
