An IoT-based Smart Home System for Disabled People

Abstract

Internet of Things (IoT) envisions a future in which physical objects and the digital world can communicate. Technical communications among appropriate information can create new categories of applications and services. Today, IoT is considered a suitable infrastructure technology for low-range wireless home control systems. In fact, smart homes and buildings provide a wide range of services, applications, equipment, networks, and systems that work together to provide an intelligent environment in areas such as security, control, communications, leisure, and comfort. The purpose of this research is an implementation of an IoT-based Smart home system that provides remote access control for disabled people to open the door lock and turn on or off the lights. Besides, this IoT-based smart home system was extended with two 2-Channel Relay Modules, which assign four keys to direct different components. In addition, this system offers a safe home environment that monitored any hazardous gas leakage, smoke, and fire, or unauthorized person. The motion sensor with a dual purpose has a bright feature that enables two applications: Energy Management System and Security System. Moreover, there are three options for users to open the door for authorized people: Using the Android application on their smartphones, voice command via Google assistant, and the "Unlock door pattern." Authorized people such as friends and family, caregivers, or dog walkers, can unlock the door by physically entering the key pattern via embedded switch buttons (doorbell, B, and C). The camera in this project gets activated as soon as someone rings the doorbell; a snapshot of the current situation behind the door will be sent to the registered user with a notification email. If the entered key pattern does not match the "Unlock door pattern," the alarm system will be triggered. The significance of this research is to provide a solution to help disabled people to live as conveniently and safely as possible in their homes.
