| Abstract: | The paper introduces the principle and characteristics of RTD accurate temperature measurement based on AD7705. The system possesses high accuracy, low cost, simple interface by integrating RTD with an A/D convertor AD7705 which has the feature of both input ports. Also the design method of C51 measuring program introduced based on MCU AT89C52. This interface is used on apparatus of measuring quantity of heat successfully. |
