Abstract
With the development of photovoltaic technology, infrared has been applied to all walks of life. Traditional thermometer--such as thermocouple, although measurement temperature range, upper value is high, but must be a contact. It creates a lot of inconvenience and the cost is high, Precision is the low，Usage is not frequent, which has been eliminated. Modern temperature adopted a non-contact in the way technology, for the problems caused by distance, using temperature compensation, improved flexibility. Because of its non-contact, not only prolong service life but also improves accuracy.
As the optical and infrared temperature measurement involves the knowledge of complex compensation circuits, and high costs, I can not be completed, instead of using another method.
The temperature monitoring system-based single-chip 8-bit AVR-based controller for a high-precision temperature sensor AD590, AD MAX1415 through the 16-bit digital conversion to be for single-chip analysis; and then single-chip analysis by software After calculating the temperature stresses through 12864 LCD, ISD1720 voice chip through the broadcast, at the same time, the analysis of numerical sent through the RF module to facilitate remote monitoring and control people. The system can accurately measure the temperature of 0.1 degrees Celsius, the system can be adopted at the same time with infrared remote control and set the alarm off the value of on-line modules, voice broadcast more humane, user-friendly LCD, but also the expansion of functions, is an ideal Monitor the temperature of the design.
