pplication of electronicРAbstract: As the technology advances in industrial production in the temperature is charged mon parameters, and the use of those charged with SCM to the parameters of control has e the mainstream. In this paper, digital temperature measurement and automatic control system design. In this paper, SCM to achieve the temperature control. It is a ponent of: AT89S51 SCM, temperature sensor, keyboard and display circuit, temperature control circuit. It can display real-time and temperature settings, and the temperature control. Passed the tests show that the design of the temperature control is convenient and simple characteristics’, thus greatly raising the temperature was charged with the technical indicators.РKey words: MCU Temperature sensor Keyboard and Demonstration
