Abstract—A Smart resistance thermometer sensor is designed to overcome the shortages of the traditional ones, and Con-form to the world development trend of the sensor market. According to the constitutions of this Smart sensor and its application coverage, those parts with good -application and low-cost were chosen to constitute this sensor on the basis of full consideration of the linkage among every part. The whole testing system were controlled and processed by C8051F350 single-chip, it could measure precise temperature by PT100 resistance thermometer and circumstance temperature for temperature compensating automatically and simultane-ously, it also could amplify signals to convert analog signals to digital ones, and display results automatically by analysing and processing information. Furthermore, it could auto-compensate self-check, and spot communicate.
Keywords—C8051F350 single-chip; PT100 resistance thermometer; Regulators source; Communication interface.
