Abstract
This paper introduces a paper counting device. The system consists of STM32 core board, FDC2214 module, OLED display module, buzzer module, key module, and two parallel plates. Two copper clad plates with a side length of 50mm square are used as capacitance plates, and the paper to be measured is placed in the middle, and the capacitance value between the two plates is collected by FDC2214 and the collected data is transmitted to the MCU controller through the IIC serial bus. The controller through the algorithm converted to the corresponding number of paper values displayed in the OLED display. The system sets self-calibration mode according to adjust the size of capacitance.
