ABSTRACT
This article describes a project for assembly, calibration and use of low cost photosensitive sensors, capable to ensure good trustworthiness, compatible with both design requirements and human being sensitivity. Tests carried through in the Faculty of Architecture and Urbanism, University of Säo Paulo, and in the School of Civil Engineering, Architecture and Urban Design, State University of Campinas, both in Brazil, with scale models under real sky conditions, had shown satisfactory performance for such photosensitive sensors for daylighting studies throughout the year, under different conditions of the luminous climate. The differential is due to its reduced cost, making affordable the use of a larger number of sensors, and the consequent assembly of a mesh of measurements, thus allowing higher detailing in the evaluations.
