Temperature controller design
ABSTRACT
In modern society, the temperature control is not only used in factory production, its action also reflect on each aspect, as people's life quality is improving, life will see temperature control shadow, temperature control will be better service to the society. Now, air conditioning and household appliances as production technology development and improvement of living standards, a simple is becoming more and more popular, stable temperature control system can better adapt to the market.
This temperature controller design, main control circuit is designed as control core AT89C52, of which the hardware part includes DS18B20 temperature sampling circuit, buttons circuit, alarm circuit, LED digital display. In coordination with C language program realization of air temperature control basic functions. This control circuit cost is low, functional practical, simple operation, and has certain practical value.
