Smart curtain was usedto shadow the evacuated tube solar collector and to control thetemperature of the Nano fluid in heating or cooling condition which ismoved by the stepper motor which is programmed to move through theArduino board using an artificial intelligence method such as (PSO basedPID) controller method . Where the curtain's main idea is to control thepolarization of the sun's radiation, the work of the curtain refers to theparameters: the first parameter is the Nano fluid temperature and thesecond is sun radiation falling on the collector, and one output parameteris defined by (distance parameter).
