Feasibility Study of Implementation of Cell Phone Controlled, Password Protected Door Locking System

Ashish Jadhav, Mahesh Kumbhar, Mahesh Walunjkar

This article summarizes the use of DTMF signalling technology to send and receive the control commands from user in order to open or close the door. Password protection is given to the system with help of microcontroller and corresponding algorithm that authenticate the user by checking the password provided by the user. So, if and only if the user press correct password then only user get authenticate and gets the access to open or close the door. Above said work has been examined theoretically as well as practically in this article. The feasibility of implementation is examined with the help of simulator which would indicate the real time results of system mentioned here.
