convert Hex result of sensor to integer value

Hi,

here is the code that I have so far:

#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // RX, TX

int sensorValue = 0;

void setup() {
  Serial.begin(19200);    // Init serial to communicate with sensor.
  mySerial.begin(9600);   // Init softserial to communicate with other device.
}

void loop() {

  // Send message to sensor, which make it send back data.
  byte message[] = { 0x55, 0xAA, 0x7E, 0x02, 0x4F, 0x43, 0x94, 0x0E, 0x0D };
  Serial.write(message, sizeof(message));

  // Read the answer of the sensor.
  while (Serial.available()) {
    int readout = Serial.read();
   
    /*** Code to interpret HEX answer of the sensor.  ***/
    
  }

  // Send the extracted sensor value to other device over softserial.
  mySerial.println("[" + String(sensorValue) + "]");

  delay(2000);
}
