This document presents a wireless embedded control system using Zigbee and ATmega32 that can be used to switch on/off indoor and outdoor LED lights and reduce light intensity to effectively reduce power consumption. This improves the energy efficiency of lighting systems while providing sophisticated control over energy usage.

1. ZIGBEE AND ATMEGA32 BASED WIRELESS DIGITAL
CONTROL AND MONITORING SYSTEM FOR LED LIGHTING
ABSTRACT:
As the world population grows, energy consumption is increasing, widening is the power
deficiency. This creates more demand for energy efficient devices in the market. The lighting
systems that are widely being used now do not employ any control energy utilization. In this
paper we present wireless embedded control that can be used for both indoor lighting as well as
outdoor lighting to switch on/off the lights and as well to reduce the light intensity of LED light
which can reduce the power consumption effectively. This improves energy efficiency of the
lighting system as well as provides a sophisticated control over the energy consumption of the
system.
