Design of a low-cost NFC Door Lock for a Smart Home System

Abstract

The Internet of Things allows computers, people, and physical electronic devices to communicate with each other in all combinations, for example, people to people, people to computer, and computer to fridge by using a Internet connection. Hence, Smart home applications are very popular nowadays. The main goal of a smart home is to improve tasks such as home monitoring or security management. In particular, digital locks have evolved by using the Internet of Things technology. In this work, we present an NFC door lock implementation that is low-cost and user friendly based on Arduino boards as the microcontroller. The main advantage of our proposed prototype is that it can be easily installed and scalable on-demand due to the devices can work independently with each other.
