Paper Counting Device Based on FDC2214

摘要

Design and make a paper counting display device. Two parallel plates (plate A and plate B) are connected to the measurement and display circuit through wire A and wire B, respectively. The device can measure and display the number of papers placed between plate A and plate B. Based on the principle of capacitance sensing, when the medium changes, it will cause the change of capacitance capacity, which will be converted into 28-bit digital output for the convenience of microprocessor acquisition and processing.
