E-sai integrated paper testing equipment

Overview

The STM32F103 microcontroller is used as the main control chip, the capacitance between the two plates is read through the FDC2214 chip circuit, and the data is processed through software to make the measured data more accurate and reliable, thereby achieving paper measurement. The screen and buttons serve as human-computer interaction functions, and the buzzer serves as a prompt after the paper test is completed.
