DESIGN AND IMPLEMENTATION OF GSM BASED SMART PHONE HOME SYSTEM. A RESEARCH PROJECT MATERIAL ON COMPUTER SCIENCE EDUCATION
1.1 Background of Study
The term “Smart Home” was first coined by the American Association of House builders in 1984 with the invention of microcontrollers (Moawia Yahia, 2014). The overall idea is to provide improved efficiency and security in their place and areas of applications.
Smart Home can be also known as Automated Home or intelligent home which indicates the automation of daily tasks with electrical appliances used in homes. This could be the control of lights, fans, viewing of the house interiors for surveillance purposes or giving the alarm alteration or indication in case of gas leakage.
One of the reasons for the rise of the smart home is the increasing risk of burglary and robbery and the busy lifestyle of people is leading to the necessity of controlling the devices at home remotely and increasing the necessity of keeping surveillance over their homes.
The goal of the project is to implement a smart home system by controlling the electronic devices at home remotely with the help of a mobile device and getting alerts on intrusion or movement around the restricted premises.
Arduino- uno Microcontroller, motion sensors, heat sensors led bulb and SIM808-GPRS/GSM module are used to design this system.
SIM808-GPRS/GSM module and the Arduino-Uno Board are used to communicate between the mobile phone and the devices and sensors installed at home. The mobile phone can be used as a controller from anywhere in the world if the GSM network is available (Patranabis, 2003).
Lifestyle in the modern society along with human behaviour and thinking is changing dramatically with the advancement of technology, and the concept of a simple home is changing into a smart home.
In the scope of industrialization, automation is step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the muscular requirement of work, automation greatly decreases the need for human sensory and mental requirements as well. Automation plays an increasing important role in the world economy and in daily experience. Automatic systems are being preferred over manual systems. This project shows the automatic control of a house as a result of which power is saved to some extent.
Home security has changed a lot from the last century and will be changing in coming years. Security is an important aspect or feature in the smart home applications. The new and emerging concept of smart homes offers a comfortable, convenient, and safe environment for occupants. Conventional security systems keep homeowners, and their property, safe from intruders by giving the indication in terms of alarm. However, a smart home security system offers many more benefits (Mior, 2009).
The advancement of technology has increased the safety and security of people along with their belongings.
Mobile phones today are not just used to make calls. The use of mobile phones is changing with the development of technology and they can be used for different purposes. They can be used as clocks, calendars or controllers instead of being used just as phones. Today smart phones are available in the market with different applications and hardware which can be implemented without any further development or enhancement. With the help of the GSM network, a mobile can be used to implement a smart home by controlling devices and getting alerts on robbery and burglary.
The cost of the system can be deter-mined by the user as the cost depends on the hardware used in the system chosen by the developer.
