Abstract
Home automation systems have attracted considerable attention with the advancement of communications technology. A smart home (SH) is an Internet of Things (IoT) application that utilizes the Internet to monitor and control appliances using a home automation system. Lack of IoT technology usage, unfriendly user interface, limited wireless transmission range, and high costs are the limitations of existing home automation systems. Therefore, this study presents a cost-effective and hybrid (local and remote) IoT-based home automation system with a user-friendly interface for smartphones and laptops. A prototype called IoT@HoMe is developed with an algorithm to enable the monitoring of home conditions and automate the control of home appliances over the Internet anytime and anywhere. This system utilizes a node microcontroller unit (NodeMCU) as a Wi-Fi-based gateway to connect different sensors and updates their data to Adafruit IO cloud server. The collected data from several sensors (radio-frequency identification, ultrasonic, temperature, humidity, gas, and motion sensors) can be accessed via If This Then That (IFTTT) on users' devices (smartphones and/or laptops) over the Internet regardless of their location. A set of relays is used to connect the NodeMCU to homes under controlled appliances. The designed system is structured in a portable manner as a control box that can be attached for monitoring and controlling a real house. The proposed IoT-based system for home automation can easily and efficiently control appliances over the Internet and support home safety with autonomous operation. IoT@HoMe is a low cost and reliable automation system that reduces energy consumption and can notably provide convenience, safety, and security for SH residents.
Highlights
Home automation systems have attracted considerable attention with the advancement of communications technology [1, 2]
Home automation systems should provide a user-friendly interface to efficiently monitor and control home appliances. To address these issues and minimize the limitations of home automation systems, the present study introduces a costeffective and hybrid Internet of Things (IoT)@HoMe automation system to extend the range of connectivity and allow users to control their homes and efficiently via a user-friendly interface using smartphones and/or laptops regardless of time and location
One of the achievements of this study is the utilization of artificial intelligence in controlling home appliances by enabling Google Assistant voice commands to help people with disabilities
Summary
Home automation systems have attracted considerable attention with the advancement of communications technology [1, 2]. An SH is a home with an automated system that comprises sensors, actuators, and controllers to enhance comfort, automation, safety, and security for a better life quality of residents [5]. Smart devices, such as smartphones, smart televisions (TVs), smart washing machines, smart refrigerators, and smart sensors, have become involved in every aspect of people’s daily lives (Figure 1). Such smart devices are capable of communicating and interacting with one another to form a smart environment [6]. Existing home automation systems lack IoT technologies and have unfriendly user interfaces. Existing systems have limited wireless transmission range connectivity because they utilize short-range wireless interfaces, such as ZigBee, Bluetooth, and Wi-Fi
