Here we are going to discuss the use of technology in field of home security. In this system, we are using ARDUINO UNO microcontroller board. This system is based on door lock security with the help of 2 high level security passwords and simultaneously the system would be connected with owner’s mobile phone through GSM Module So that the owner could open the door from remote location also. When any authorized would try to open the door, he would have to enter 2 passwords when asked to do so. If he enters right passwords then the door will get open.
