A Microcontroller-Based Light Intensity Adjustment of a Classroom Taking Into Consideration the Distribution of People

Nowadays energy conserving has become one of the most important approaches that concern governments, companies, universities, and even individuals. This rising concern is coming from the fact that the world currently suffers from rising fuel costs. This requires us humans and especially engineers to come up with solutions in which we can either find a way to reduce fuel costs, such as finding a replacement to provide us with the needed energy, or we can optimize the usage of the energy and fuels we have right now. This paper focuses on the second approach, in which we are trying to make lighting as energy-efficient as possible. This requires us to optimize lighting systems by using modern and energy-efficient technologies. Lighting systems being the subject of this paper comes as one of the best systems to apply solutions in which we reduce the energy consumption while keeping the performance as good as it is, if not better. And this is because lighting systems exist everywhere, offices, houses, companies, schools and universities, which make the benefits coming from the system we are proposing being folded multiple times, thus the effect will be way larger than any ordinary approach that targets system not as spread as lighting systems. In our proposed technique, we are applying lighting control system, which controls the intensity of lights in a class room. The results were as expected, applying such technology in a university for example will make the university a lot more energy-efficient than it is currently, in addition the university will witness a large cost reduction in terms of bills, and also will have a more advanced and healthier environment
