Smart Locking System Based on Arduino and Raspberry Pi

This paper proposes a new reliable and technology-based security system that is one of the most sought-after things in order to ensure security in an organization/building. The security of a place can be much better if there can be double-layered authentication of the authorized persons. Also, there are a number of instances where people are supposed to be away from their location and someone else from their organization needs to access the place in their absence. In these kinds of situations, monitoring the visitor and giving access from a remote place are what most people desire. A smart IoT-based security system can provide multi-layered security for authorized users and can also remotely monitor the system to give access to other unauthorized users after proper authentication.
