Smart Home Door Unlocking System Using PIC16F877A

The Internet has become an integral part of human life in such a way, that most of the applications become helpless without internet. To make most use of this, this paper proposes a smart unlocking mechanism for doors of high security importance. This is made possible by employing IoT Technology, which not only controls, but also effectively monitors electrical and mechanical system. In this method, the doors are operated using mobile app, even at remote places. A hardware prototype has been developed and tested by integrating Special Electrical Machines, PIC Controller and GPS Module. The results seem to be satisfactory, by providing a smart and secure way of door control.
