초록
In this paper, we proposed digitalized low cost data logger system. In the past, data logger system which use analog method had many problems, inconvenience of measurement, unsatisfied accuracy, and had difficulty in storing data. Proposed system overcome these problems by using one-chip microcontroller which detects abnormal satus and saves it in RAM card. Saved data are transmitted to personal computer by serial communication port and by parallel interface card. Field experiment results validate the performances of the proposed system.
