Implementation of an intelligent blind control solution

Solar protection systems compose an important role in selective control of solar radiation in the interior environment, thus interfering with the luminous, thermal and energetic performance of buildings. This work aims to study factors that influence a better use of incident solar radiation on glazed surfaces and how electric blinds can act at strategic moments in order to potentiate this utilization. The proposed methodological strategy involves analysing the relationship between luminosity values, evaluated by sensors, compare it to solar radiation values measured by a weather station, in order to obtain a useful correlation to operate the most favourable opening and closing adjustment points. In order to be able to apply this analysis, a prototype was developed for automate the operation of opening and closing the blinds, through the integration of sensors, microcontroller and the entire electronic and logic system that ensures such functionalities. This prototype is designed to be compact and easy to install and can be assembled in the most common switch boxes.
