Description: The design is applied for MCS-51 series MCU AT89C51-type sampling, compare and control. The main content of this research are: (1) the temperature detection process using the link Pt100 platinum resistance temperature measurement devices as, Pt100 with stable performance, strong antioxidant properties and high precision measurements, more accurate measurement can be achieved temperature. Acquisition and conversion process data acquisition system (2) of the data is a computer for control and data processing system, realized by using ADC0804 analog to digital conversion. (3) temperature control process using an interrupt, when the end of the A/D conversion, an interrupt request, the MCU responds to the request, the driver relay, heating or cooling process. (4) Display process uses two LED digital display temperature to achieve on-site.
