Abstract

Abstract: In order to measure the quantity of paper with high speed and accuracy, a new measuring technology based on the principle of capacitance sensing is proposed and a measuring device is made. Put two metal plates of the same size at a certain distance with a piece of A4 paper in the middle. When the thickness of the paper changes, the capacitance on the metal plate will change. Use the capacitance sensor fdc2214 to sense the change. After modeling and analysis, determine the functional relationship between the thickness of the paper and the measured value, and calculate the paper quantity. The test results show that the device can count the number of paper accurately and quickly.
