Problem Statement

There are many strategies and concepts in designing and implementation home automation solution. To control the electric aplliance at home is sometimes trublesome especially to switch on the socket when the devices is used and to turn off the device when finish.If the switch is need to be off, someone must push the switch to off then the device will off. If the switch is far away from the people and he/she are tired to go far to turn off the switch, then the electric device will be leave on. There will be a wasted of electrical energy if the device that unused in still on.

Other than that, to switch off the switch, an operator or someone need to touch the switch to turn the switch on or off. If the user of the switch have a wet hand, the user have the risk to get the electric shock because of the spark that produce when we push the switch at the socket.

From the above statement, this project is develop to overcome the problems that occur with the ordinary switching system. The remote control that capable of controlling the switch will bring a new level of comfort in our life. The house device like air-condiion,heater,fan and light can be ON from a specific distance. The application of this system is numerous and a step closer to usage of controlling intelligent house.

RF module

RF receiver module

These RF receiver modules are very small in dimension. The low cost RF Receiver can be
used to receive RF signal from transmitter at the specific frequency which determined by the product specifications. Super regeneration design ensure sensitive to weak signal. In this project,RF Receiver Modules 315MHz is used.


RF transmitter module

These RF Transmitter Modules are very small in dimension and have a wide operating
voltage range (3V-12V). The low cost RF Transmitter can be used to transmit signal up to100 meters (the antenna design, working environment and supply voltage will seriously impact the effective distance). It is good for short distance, battery power device development. In this project,RF transmitter Modules 315MHz is used.

Wireless Remote Controlled Power Socket

INTRODUCTION


This control socket allows you to turn the power to your appliances and equipment on and off by remote control. Each socket learns the code from the button/channel on the remote control transmitter that assigned to the socket.You can then turn the power supply to any equipment connected to the socket on or off from a distance, just by pressing a button.

This makes it very simple to turn many pieces of equipment off from a single remote control unit. No more excuses for not turning off the TV, stereo, lamps etc. Once turned off they will use no electricity, so no more standby energy is been wasted.So you have complete flexibility. It will work through walls and ceilings up to a certain distance.

This wireless remote control socket also is an electric socket that the switch is controlled by a radio or other signal and does not require an operator to touch the switch. The remote control device, if electrically operated, uses batteries with a low, safe, voltage. Such a switch avoids the risk of electric shock if a user touches a switch with wet hands, and allows switching apparatus from a location without a wired switch.

For this project, we want to control more than one socket using the remote control. A receiver can control about three power socket and mainly controlled by the transmitter for the switching purpose.
