Design of a microcontroller based automated pyranometer

Abstract

An experimental system for measuring the intensity of solar radiation has been developed; it is done based on a microcontroller and can measure eight signals at programmable time intervals. The data are acquired from sensors are placed on a dome to monitor and measure the insolation during the whole day. Thanks to the technology used the system has a large autonomy of use, which allowed us to measure the sunlight with an accuracy of about 0.1%.
