1. MORE EFFICIENT HOME ENERGY MANAGEMENT SYSTEM
BASED ON ZIGBEE COMMUNICATION AND INFRARED
REMOTE CONTROLS
Abstract:
This paper describes more efficient home energy management system to reduce power
consumption in home area. We consider the room easily controllable with an IR remote control
of a home device. The room has automatic standby power cut-off outlets, a light, and a Zigbee
hub. The Zigbee hub has an IR code learning function and educates the IR remote control signal
of a home device connected to the power outlet. Then the power outlets and the light in the room
can be controlled with an IR remote control. A typical automatic standby power cut-off outlet
has a waiting time before cutting off the electric power. It consumes standby power during that
time. To eliminate the waiting time, we turn off the home device and the power outlet
simultaneously with an IR remote control through the Zigbee hub.
Existing system:
As more and more home appliances and consumer electronics are installed, residential
energy consumption tends to grow rapidly. A large number of home devices increase power
consumption in two aspects, standby power and normal operation power. Those two kinds of
power consumption are proportional to the number of home devices. As a result, Standby power
is electricity used by appliances and equipment while they are switched off or not performing
their primary function. As around 10 % of a total household power is consumed during standby
power mode, the reduction of standby power is greatly necessary to reduce the electricity cost in
home in this project application.
Proposed System:
In this project we introducing a new technique in this application, here we are using a
microcontroller, zigbee transceiver, IR TV remote controller, and relay to operate electrical

2. equipments. Here the method to operate devices using IR TV remote and Internet also. With the
help of microcontroller to On/Off devices and the status should be displayed in LCD display and
this information is up dated in the Internet. By accessing the internet the user may came to know
that what are the devices are running in the home using Zigbee wireless communication. The
user wants to control means these electrical devices. He may control it through internet itself. Or
if he is in the Home, he may control it through IR Remote controller technique. Through this we
could achieve the Home Energy Management.
