Which Serial port is connected to the sensor? Serial0? If not, then you can connect the Arduino to the PC with USB and read data from the serial port.

Hi,

In MATLAB,

use device() to connect to serial device on Arduino

arduinoObj = arduino("COM16","Leonardo","Libraries",{'SPI','Serial','I2C'})
% For accessing TX2/RX2
serialdevObj = device(arduinoObj,'SerialPort',2)
write(serialdevObj,[88 99 65]);
