Tital:Design of Temperature Measurement Based on Single Chip
Abstrat:Temperature measurement is an important part in the industries. Quartz Crystal has the following merits : high sensitivity to temperature .good linearity and so on. Based on the above merits .a high precision temperature measurment with digital .And we design a digital filter realizing by software to reduce the measure noise .This paper illustrates the hardware structure and software design of the temperature measurement system. The experiment results show that the system has the reasonable design,the good dependability and high measurement precision.
Keywords:temperature measurement ;single chip; digital filter ;80C552
