Temperature-Meter via USB Base Don PIC 18F2550 for Solar Energy Concentrator System

A study of a novel temperature measurement system is presented this system is with direct connection to the PC used to measure temperature in an optical system of concentration of solar radiation. The system will measure the temperature in the focus of the parable of the system and transmit the information via the USB (Universal Serial Bus) to a computer for later analysis. The system is based on a microcontroller PIC 18F2550 this microcontroller has ten analog-to-digital converter (A/D) channels and also has a USB version 2.0 slave module, the temperature sensing is done through a thermocouple type K. In this work the theoretical and practical optical system, describes the necessary characteristics of the measurement system and its purpose within the research project on renewable energy held by the Polytechnic University of Puebla. The second part presents the implementation of the temperature system as well as the development of the program that receives, analyzes and saves the data received by the meter temperature. Finally, we present the results of the measurements in the field and a projection system for the future.
