| Abstract: | In order to solve the problem of electronic balance accuracy caused by weak signal amplification,a high-precision chip ADS1230 was used,the trouble of designing analog amplifier was eliminated.And it was solved that the problem of offset voltage and temperature drift caused by analog amplifier.The resistance strain sensor works,chip ADS1230 features and its application circuit design were discussed.Then the microcontroller AVR-mega16 was used to design an electronic balance,and the design methods of hardware system were illustrated.The results of experiments show that the accuracy is up to 0.05 g,and the system has characteristics of weighing fast,data stable. |
