Abstract
The light is a natural power source which allows the human to accomplish the majority of their activities. When the night falls is indispensable to have good light conditions to do some usually human activities, like for example driving, also it is necessary to know the most suitable lighting level for light conditions of the environment in order to optimize the process and use the least amount of energy possible. In this project some components, which detect the illuminance and transform it in electrical signals, are analysed. Also three experiments are conducted in order to characterized and validate the options of using LEDs for this purpose. Finally and due to the results obtained another solution is given, which is more suitable for this objective, it is proposed at the end of the project.
