ABSTRACT:
A system of automatic acquisition data, the Micrologger 21X, was used to obtain an output of instantaneous values of the components of the solar radiation, every 5 minutes. The “Microcal OriginTM” environment was used to develop a software for create curves of the instantaneous radiation values of the components the solar radiation (global, diffuse, reflected and net radiation) and to make the integralization of its values, along the day, in MJ.m-2. That software improved the efficiency of treatment of instantaneous and daily data, components of the solar radiation, facilitating data manipulation and providing larger speed and reliability in the obtained results.
Keywords: automatization, programming, solar radiation.
