Designed a utility model computer temperature acquisition system, using AD590 as a temperature sensor, ADC0809 for analog-to-digital converter. The principle of the system is simple, compact, low cost, applicable to multi-point temperature measurement occasions, are widely used in industrial production and people' s daily life, and shows the superiority of economic, reliable. In this paper, the principle of the various components of the system function, circuit diagrams, function of the chip made a detailed introduction to measurement error in line with the requirements specified by the system.
