1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
With the increase in consumption of energy and population, there is a grave need to conserve energy in each way possible. The inability to access and control the appliances from remote locations is one of the major reasons for energy loss. A web or an android application is used by the consumer to give instructions to these systems. This system can make use of a host of communication methods such as infrared, Wi-Fi, GSM, Bluetooth, ZigBee, Radio Frequency. Different controlling appliance and configurations can be found in existing systems. Such systems have been found already in many places for a wide variety of applications.
The home automation systems provide mutual interoperability among various electronic, electrical, and power appliance as well as interactive interface for people to control their operation. These features are very helpful to optimize and to economize energy consumption whereby saved energy during some few years could make more money than home automation systems implementation cost. These technologies make peoples’ life also easier, especially for elderly persons and persons with disabilities. These systems exist of course, but there are many non-interoperable, expensive, and often wired systems. Wiring complicates implementation of the home automation in buildings which are already built, especially in historical ones.
The goal of this project is to develop a secure Home Automation System that will allow consumer to remotely operate electric home appliances, e.g. turning on/off lights, in the user’s home.
The consumer interacts with the Home Automation System through computer. This will provide a consumer-friendly interface for the consumer to access and interact with the electric appliance in the home.
Examples of practical uses for such home automation system are many. These include;
- Smart house
- Small-Range wireless network
- Wireless meter reading
- Access control systems
- Wireless home security systems
- Industrial Area paging
Home automation also known as domestics refers to the automatic and electronic control of household features, activity, and appliances. Various control systems are utilized in this residential extension of building automation. Some components of an automated home may include the centralized control of security locks on doors and gates, appliances, windows, lighting, surveillance cameras and HVAC systems heating, ventilation and air conditioning.
This paper presents design and construction of a radio frequency based electrical appliances controlling system using remote. The remote acts as a modem for the control of electrical home appliances. This is achieved when the button is pressed and an appropriate command button is pressed. The paper demonstrates how to develop a system that aids the control of remote devices using remote to enable devices without infrared though connected to power sources to be controlled and considering the possibility of users to monitor the status and usage of these devices.
1.2 PROBLEM STATEMENT
Most homes make use of many electrical and electronics appliances such as the television set, standing fan, ceiling fan, air conditioner, lighting bulbs, video players, radio, etc. All these appliances require switching to turn on and turn off these appliances traditionally. This manual switching of any home appliance is an inconvenient method for physically disabled or elderly or even for the young and busy individuals when frequent switching operation is required. Thus, an easier method of switching is developed to replace this manual switching method, using an advanced switching method for electronic home appliances – ir remote control. This involves using remote to switch ON and OFF of home appliances.
1.3 AIM OF THE PROJECT
The aim of this work is to build a remote control device for home appliances let the user to connect your regular everyday appliances to be controlled by a remote. All you have to do is connect this circuit to any of your home appliances (air conditioner, fan, ac socket etc) and you are good to go. The appliance can now be controlled by a remote control working at the designated frequency. The circuit can be activated from up to 10 metres.
1.4 OBJECTIVE OF THE PROJECT
The main objective of this project is to develop a home automation system with a four button key transmitter by using infrared technology.
1.5 PURPOSE OF THIS PROJECT
The main purpose of this project is to develop a home automation system with remote control. As technology is advancing so houses are also getting smarter. Modern houses are gradually shifting from conventional switches to centralized control system, involving wireless controlled switches.
Presently, conventional wall switches located in different parts of the house makes it difficult for the user to go near them to operate. Even more it becomes more difficult for the elderly or physically handicapped people to do so. Remote controlled home automation system provides a simpler solution with an infrared technology.
By operating the specified remote switch on the transmitter, the loads can be turned ON/OFF remotely through infrared technology.
