The Temperature Controling System of Single Chip Microcomputer Abstract: This design sources the practice of work and science. The application of digital temperature controller is very extensive in the field of industry and automation. The digital temperature controller has a good application foreground. This design presents the advantage that uses K type thermocouple handled device MAX6675 to design digital temperature controller, and then introduces work principle and characteristics of MAX6675.This design shows the hardware realize and software design of digital temperature controller that bases on 89C51 signal chip-micro computer. Hardware design is mail and software design is the next important in this design. This design includes measurement, Man-machine interface , and main control. The above three parts are the core of this design. The devices of this design is economic and practical. This design is very clear and simple. It has a application. Because industry and automation develops fast, so the digital temperature controller must have a good application foreground.
