What is home automation?
Home automation is the process of using technology to control and monitor various aspects of a home, such as lighting, temperature, security, entertainment, and so on. Home automation can provide convenience, comfort, safety, energy efficiency, and cost savings to the homeowners. Home automation can also enable remote access and control of the home appliances via smartphones, tablets, computers, or other devices.
Why use GSM for home automation?
GSM stands for Global System for Mobile Communications, which is a standard for mobile communication networks. GSM can be used for home automation because it offers several benefits, such as:
Wide coverage: GSM networks are available in most parts of the world, so you can control your home appliances from anywhere with a GSM signal.
Low cost: GSM modules are relatively cheap and easy to obtain, so you can build your own GSM based home automation system without spending too much money.
Simple operation: GSM based home automation system only requires a SIM card and a mobile phone number to operate. You can send SMS commands to the system to turn on or off your appliances.
Reliable communication: GSM networks are robust and secure, so you can communicate with your system without worrying about interference or hacking.
Objectives of the project
The main objectives of our project are:
To design and construct a GSM based home automation system that can remotely control electrical appliances via SMS commands.
To test and evaluate the functionality and performance of the system in terms of accuracy, response time, reliability, and user-friendliness.
To compare our system with other existing systems in terms of features, advantages, disadvantages, challenges, and limitations.
To demonstrate the feasibility and usefulness of GSM based home automation system for various applications and scenarios.
Literature Review
In this section, we will review some of the previous works on GSM based home automation system. We will also discuss their advantages and disadvantages, challenges and limitations.
Previous works on GSM based home automation
There are many examples of GSM based home automation systems in the literature. Here are some of them:
In 2009, Das, Sanaullah, et. al. [13] developed a cell phone based remote management and control system for home appliances. However, a few limitations for the system include not being able to control multiple appliances concurrently and the home automations system could not verify the status of the appliances.
In 2010, Alkar and Buhur [14] proposed an Internet based wireless home automation system for multifunctional devices. The system used a web server and a GSM module to communicate with the devices. However, the system required a constant Internet connection and a high power consumption.
In 2011, ElShafee and Hamed [15] designed a smart home control system using Bluetooth technology and a microcontroller. The system used voice commands to control the appliances. However, the system had a limited range and was prone to noise interference.
In 2012, Teymourzadeh, Ahmed, et. al. [16] presented a smart GSM based home automation system that used SMS commands to control the appliances. The system used a PIC microcontroller and a GSM module to communicate with the devices. The system also provided feedback status of the appliances via SMS. However, the system had a high latency and a low security.
In 2013, Kumar and Lee [17] proposed a Zigbee based home automation system that used wireless sensors and actuators to monitor and control the appliances. The system used a Zigbee coordinator and a web server to communicate with the devices. The system also provided a graphical user interface for the user. However, the system had a high cost and a complex installation.
