How to convert data that displayed in Serial Monitor to binner

My plan is to convert data serial print in void tampil to binner,and in the below are the code
Anyone know how to convert that?
Thanks

#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>

RF24 radio(9, 10); //CE dan CSN

const byte node1[5] = {'N','x','A','A','a'};
const byte node2[5] = {'N','x','A','a','A'};
const byte node3[5] = {'N','x','a','A','A'};
const byte sink[5] = {'S','X','a','a','a'};

char perintah[11] = "Pesaaan 0";
char counter = '0';
char node = '0';
bool databaru = false;

typedef struct{
  float A;
  float B;
}tipebaru;
tipebaru data;

unsigned long currentMillis;
unsigned long prevMillis;
unsigned long txIntervalMillis = 5000; // send once per 5 second

//============

void setup() {

    Serial.begin(1200);

    radio.begin();
    radio.setDataRate( RF24_250KBPS );
    radio.openReadingPipe(1, sink);

    radio.setRetries(3,5);
    kirim();
    prevMillis = millis(); // set clock
}

//=============


void loop() {
    currentMillis = millis();
    if (currentMillis - prevMillis >= txIntervalMillis) {
        kirim();
        prevMillis = millis();
    }
    ambildata();
    tampil();
}

//====================

void kirim() {       
        ganti();
        radio.stopListening();
            bool rslt;
            rslt = radio.write( &perintah, sizeof(perintah) );
        radio.startListening();
        Serial.print("Data Sent ");
        Serial.print(perintah);
        if (rslt) {
            Serial.println("  Acknowledge received");
            counter1();
        }
        else {
            Serial.println("  Tx failed");
            Serial.println(" ");
            counter1();
        }
}

//================

void ambildata() {

    if ( radio.available() ) {
        radio.read( &data, sizeof(data) );
        databaru = true;
  }
      
}

//================

void tampil() {
    if (databaru == true) {
        Serial.print("Suhu = ");
        Serial.print(data.A);
        Serial.print(" C, Kelembaban = ");
        Serial.print(data.B);
        Serial.println(" %");
        Serial.println();
        databaru = false;  
    }
}

//================

void ganti() {
      if (node == '0'){
        radio.openWritingPipe(node1);
    }
    else if (node == '1'){
        radio.openWritingPipe(node2);
    }
    else if (node == '2'){
        radio.openWritingPipe(node3);
    }
    counter2();
}

//================

void counter1() {
        // so you can see that new data is being sent
    counter += 1;
    if (counter > '2') {
        counter = '0';
    }
    perintah[9] = counter;
}

//================

void counter2() {
  node += 1;
  if (node > '2') {
      node = '0';
  }
}

The data already is in binary - no conversion necessary.

If I want to sent the data from Arduino to modulator FSK,which port (data that Serial Monitor displayed) that should be connected with the Modulator? Is Tx port?

AWOL:
The data already is in binary - no conversion necessary.

It may depend on which Arduino you have but in general, connecting TX to the serial input of the modulator would be the right thing.

But we are missing so much information on what you want to do. What is this modulator? (Not the NRF24, I hope?) Which data did you want to send in binary? data.A and data.B? What is on the other end to receive the data?
