16-channel analog multiplexer (MUX, CD74HC4067): 0
The analog voltages were read via the analog-digital converting pins in the Arduino Nano Microcontroller. We connected a load resistor of 100 MΩ to each sensor and applied an offset of 3.3 V to measure the analog voltage output in the positive value region. The sampling rate was 300 Hz. A personal computer (PC) used for data processing was connected to the microcontroller through serial communication. For the full testing of the 2 × 2 sensor array, a 16-channel analog multiplexer (MUX, CD74HC4067) was used to measure 12 signals and was controlled via the microcontroller. The sampling rate was adjusted to 50 Hz since the number of sensors increased.
