IoT Based Door Entry System

Objectives: This paper proposes a remote access controlled door entry system for homes and office buildings. Methods/ Statistical Analysis: A remote access control system comprises of the internet to control the devices and appliances at home or office with the person controlling them from anywhere around the globe. In our proposed system, a Raspberry Pi board is used as the platform for monitoring and controlling the door lock. The door entry system proposed here consists of a switch for guest monitoring, camera for guest authentication, solenoid actuator for opening of the door and a speaker set for making the system intimate the responses to the guest. Switch, speakers and camera for interaction with the guest are mounted at appropriate places at the door. Findings: Status of the switch can be monitored by the Raspberry Pi. As the guest presses the switch on arriving at the door, the door entry system enables the host to conveniently monitor and control the entry of people to the house through Internet. Application/Improvements: The main advantage of our proposed system is that it can be easily used in home without requirement of any new software installation and configuration. In future, Instead of monitoring switch status, interrupt driven method can be used to monitor the person.
