AN IR AND ZIGBEE-TO-ZIGBEE SCHEME FOR
CONTROL OF MULTIPLE DEVICES

ABSTRACT
Remote control is already part of the everyday Life.However, there is no truly single remote which can Control all appliances at home.There are many various CE (Consumer Electronics) home appliances being controlled and managed with each different remote control based on IR (Infra-Red) signal in our home environments. To control them based on IR control signal, the remote control unit has to have many pre-programmed control codes for controlling them. In this paper, we propose a scheme for control of CE devices with URC (Universal Remote Control) by using IR whose distance will be short distance and line of sight only.This Can be solved by the combination of IR and ZigBee.In this scheme , we can configure controllable CE devices based on user’s mobility and minimize power consumption.
INTRODUCTION
Many various home appliances, most of which are controlled by IR (Infra-red) [1] signal based remote control unit, are used in today’s home environments. A URC unit is an integrated device for controlling many different consumer electronics(CE) appliances.To control these various CE devices by using IR control signal, the remote control unit has to have many pre-programmed control codes for controlling them because they are controlled with many different types of IR codes stated with leader code, control code,carrier frequency.In addition to this difficulty, the IR based remote control any devices under the only condition of line of sight. In this paper, we propose a scheme for control of multiple devices based on ZigBee modules.It is very difficult on order to control all home appliances with different remotes. It’s very annoying to consumers. The Scheme uses a URC unit but the transmission from IR to ZigBee must be in line of sight only. A URC is used to control these devices by IR based remote but by using IR we cannot operate all these devices because IR operates in line of sight communication mode and it cannot penetrate through walls. In order to avoid this drawback we used ZigBee when compared to IR the range of zigbee is more .But the control of first CE device must be line of sight only then by using IEEE802.15.4 we can operate from different rooms.In this paper, we proposed device control scheme in order to operate CE [2]devices but we cannot operate all these devices with IR so we used zigbee to operate from different rooms and the use of zigbee is it is a wireless network. Now a days, it is used widely and it does not need much power, so batteries will last upto 10 years.This paper show the implementation of the URC mechanism by using ZigBee applicable to control all CE devices from different rooms . The remainder of this paper is organized as follows.We first describe and review ‘IR remote control’being used in CE appliances to control them and introduces URC to control many home appliances with a remote control unit.We then show the implemented hardware results and illustrate their operation.Finally, we present our conclusion.
