The design, implementation and results of a control, monitoring and storage system for the parabolic compound solar collector temperature data are shown. A fluid’s temperature that circulates through the colector’s receptor tube is sensed in diferent points with type J thermocouples whose signals were amplified to voltage levels that are compatible with the input voltage range of an A/D converter residing in a PLC’s analog input module. The CPU of the PLC calculates the temperature sensed by each thermocouple and executes a control algorithm which holds the temperature of the fluid, at the colector’s output, in a setpoint value configurable through a matricial keyboard and a liquid crystal display. The control is achieved varying , with an electrovalve, the flow so that the plant’s disturbances are compensated. Additionally, a module based on a Freescale MCHC908GP32 microcontroller that allows to store temperature data in an EEPROM flash memory was implemented. The stored temperature data are downloaded to a PC through a graphic application.
