| Abstract: | An intelligent device applied in photoelectric effect experiment and a implementation scheme using chip microcomputer-based system to establish the intelligent device experiment system were introduced.The system schematic diagram and the operating measurement principle were illustrated also.It was proposed using the measure plan method of Zero and inflection point simultaneously,to solve the accuracy problems of long time measuring and environment exchanging,to reduce experiment error and disturbed opportunity of weak photoelectric current,to actualize rapid and accurate measurement. |
