Abstract
The disclosure provides a data acquisition device. The data acquisition device includes a sensor that detects a physical quantity as analog data; a digital storage circuit that stores the physical quantity as digital data; a difference circuit that calculates a difference between a previous value of the physical quantity stored in the digital storage circuit and a current value of the physical quantity detected as analog data; and a comparison circuit that compares the difference with a predetermined threshold value; and a control unit. The control unit stores a value calculated by adding or subtracting a predetermined change amount to a previous value of the physical quantity stored in the digital storage circuit as the current value, when the difference exceeds or falls below the threshold value. Since the physical quantity is updated without executing A/D conversion, a decrease in the sampling frequency is suppressed.
