%X The ways which
are used today in order to light houses, offices, and most of </span><span style=\"font-family:Verdana;\">the </span><span style=\"font-family:Verdana;\">indoor areas are inefficient as a lot of energy is
consumed unnecessarily during the day time. Mainly this problem</span><span style=\"font-size:10pt;font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">because the interior
lighting design consider the worst case when the light service is at night, </span><span style=\"font-family:Verdana;\">which</span><span style=\"font-family:Verdana;\"> is not always valid.
Also in most cases the lighting system design rel</span><span style=\"font-family:Verdana;\">ies</span><span style=\"font-family:Verdana;\"> on people to control the lights switching on and
off. This problem is also one of the design concern</span><span style=\"font-family:Verdana;\">s</span><span style=\"font-family:Verdana;\"> in Green Building. In this paper, a solution to
this problem and a method for people¡¯s comfort who use the indoor facilities in
industrial building</span><span style=\"font-family:Verdana;\">s</span><span style=\"font-family:Verdana;\"> is presented. In the proposed smart lighting system, lights switch on
automatically when there is somebody in the room or in the occupied space and
switch off when there is no occupancy. In addition to this known technique,
adjustment of the brightness level of the lights will be possible via the
personal computer or any other smart device. In this method, for the
illumination level in the area, where is needed to be controlled for better
energy saving, </span><span style=\"font-family:Verdana;\">the </span><span style=\"font-family:Verdana;\">light automatically is measured by </span><span style=\"font-family:Verdana;\">the </span><span style=\"font-family:Verdana;\">sensor and considering the amount of background
lights coming from outside, automatically the brightness of lights is
controlled to reach the preset level that determined for that room. By the
means of this method, it is possible to provide better user comfort, avoid
human forcedness to switch the light on and off, and hence effective energy sav</span><span style=\"font-family:Verdana;\">ing</span><span style=\"font-family:Verdana;\">. Arduino controller
is used to build the controller and to demonstrate the results. Economic
analysis was done to calculate the percentage of the energy saving that can be
obtained by implementing the proposed smart lighting controller. As an outcome </span><span style=\"font-family:Verdana;\">of </span><span
