Specification

Description

The main objective of a keyless mobile-controlled locks system is to unlock a garage door (different types of the door) by a mobile phone using a unique password entered through the phone's keypad. Opening and closing garage doors involves human labor. In this password system, the opening and closing of a garage door are achieved by using a mobile phone. The owner can call a mobile phone interface to the system which in turn is connected to the garage door that can open/close the door by entering the password.

This kit is based on the concept of DTMF (dual-tone multi-frequency) technology. Every numeric button on the keypad of a mobile phone generates a unique frequency when pressed. These frequencies are decoded by the DTMF decoder IC at the receiving end which is fed to the microcontroller. If these decoded values (password entered by the user) matches with the password stored in the microcontroller, then the microcontroller initiates a mechanism to open the door through a motor driver (L293D IC) interface.

The objective of this DTMF Controlled Door Lock kit is to develop a device that allows a user to remotely control and monitor a garage door using a cellular phone. This system is powerful and provides such service at any time and from anywhere.
