Reducing energy demand in the residential and
industrial sectors is an important challenge worldwide.
In particular, lights account for a great portion of total energy
consumption, and unfortunately a huge amount of this energy
is wasted. Light-emitting diode (LED) lights are being used to
light offices, houses, industrial, or agricultural facilities more efficiently
than traditional lights. Moreover, the light control systems
are introduced to current markets, because the installed lighting
systems are outdated and energy inefficient. However, due to
high costs, installation issues, and difficulty of maintenance;
existing light control systems are not successfully applied to
home, office, and industrial buildings. This paper proposes a low
cost, wireless, easy to install, adaptable, and smart LED lighting
system to automatically adjust the light intensity to save energy
and maintaining user satisfaction. The system combines motion
sensors and light sensors in a low-power wireless solution using
Zigbee communication. This paper presents the design and implementation
of the proposed system in a real-world deployment
