Abstract
A device that can measure the amount of paper, display it, and announce it by voice is designed. The hardware part of the device consists of two metal plates, a capacitor voltage detection circuit and a single-chip microcomputer; the software part uses the least square method for linear fitting, which reduces the amount of data required for system self-calibration, and uses statistical principles to reduce linear errors, which improves the accuracy of discriminating the number of sheets of paper.
