JIMENEZ HERRERA, Joe Alexander; ORTIZ ARROYAVE, Luís Fernando; POSADA, Gildardo  e  CARRILLO, Orlando. Design and implementation of a data acquisition system to measure local solar power. rev.ing. [online]. 2006, n.23, pp.42-47. ISSN 0121-4993.

The present work deals with the measurement of the direct, global and diffuse components of the solar radiation, through pyranometers, with the signs adaptation right and the digitalization of them in the microprocessor HCS12. The data storage is effected through memories I2C, achieving a capture capacity of 13 days approximately, storing 3 data by minute during the "solar day". Besides, it counts with a visualization and serial communication interface constituted by a PC, a LCD and a keyboard with which it allows modifying the system parameters.
