The ways which
are used today in order to light houses, offices, and most of the indoor areas are inefficient as a lot of energy is
consumed unnecessarily during the day time. Mainly this problembecause the interior
lighting design consider the worst case when the light service is at night, which is not always valid.
Also in most cases the lighting system design relies on people to control the lights switching on and
off. This problem is also one of the design concerns 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 buildings 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, the light automatically is measured by the 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 saving. 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 of
