nRF24l01 multiple transmitters to one receiver

Using Arduino Networking, Protocols, and Devices

Hey, people, I have a problem with my project

I want to create a home security system and I'm coming to a problem where my Arduino does not receive data from the other two nrf2401 transmitters

Heres the code of my receiver:

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


  
  

RF24 radio(9, 10);
byte address[][6] = {"0"};

//second reciever
RF24 radio1(9, 10);
byte address1[][6] = {"1"};

void checkForWirelessData();
  
 void checkForWirlessDatasecond();




void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  
  
    
   
    
     radio.begin();
    radio.setChannel(124);
    radio.setPALevel(RF24_PA_MAX);
    radio.setDataRate(RF24_250KBPS);
    radio.openReadingPipe(1,address[0]);
    radio.startListening();

    
    radio1.begin();
    radio1.setChannel(123);
    radio1.setPALevel(RF24_PA_MAX);
    radio1.setDataRate(RF24_250KBPS);
    radio1.openReadingPipe(1,address[0]);
    radio1.startListening();
  }
 
  

  



void loop() {
  // put your main code here, to run repeatedly:
  void checkForWirelessData();
  
 void checkForWirlessDatasecond();
  

  

}


    


void checkForWirelessData(){
  char data;
  if(radio.available()){
    while(radio.available()){
      radio.read(&data, sizeof(data));
      if(data == 11){
       
        Serial.println("Motion Detected At Kitchen");
        
      }
     
    }
  }
}

void checkForWirelessDatasecond(){
  char data2;
  
  if(radio1.available()){
    while(radio1.available()){
      radio1.read(&data2, sizeof(data2));
      if(data2 == 11){
       
        Serial.println("Motion Detected At Bathroom");
}
    }}}

and my first transmitter:

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

int stabilize = 30;
int pirState ;

RF24 radio(9, 10);

byte address[][6] = {"1"};
int PIRpin = 3;
int val;

void setup() {
  // put your setup code here, to run once:
  

  radio.begin();

  radio.setPALevel(RF24_PA_MIN);

  radio.setDataRate(RF24_250KBPS);

  radio.setChannel(123);

  radio.openWritingPipe(address[0]);
  radio.stopListening();

  
  pinMode(PIRpin, INPUT);

  

}

void loop() {
  // put your main code here, to run repeatedly:
  
  readSensor();
  radio.write(&val, sizeof(val));
  delay(1000);
  

   

}
void readSensor(){
  int message[1]= {00};
   val = digitalRead(PIRpin);
  if(val==HIGH){
   
    
    if(pirState == LOW){
      message[0] = 00;
      radio.write(message,1);

      pirState = HIGH;
    }
  
  }else if(pirState == HIGH){
    message[0] = 11;
      radio.write(message,1);

      pirState = LOW;
  }
}

and second with only a small change:

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

int stabilize = 30;
int pirState ;

RF24 radio(9, 10);

byte address[][6] = {"0"};
int PIRpin = 3;
int val;

void setup() {
  // put your setup code here, to run once:
  

  radio.begin();

  radio.setPALevel(RF24_PA_MIN);

  radio.setDataRate(RF24_250KBPS);

  radio.setChannel(124); //over here

  radio.openWritingPipe(address[0]);
  radio.stopListening();

  
  pinMode(PIRpin, INPUT);

  

}

void loop() {
  // put your main code here, to run repeatedly:
  
  readSensor();
  radio.write(&val, sizeof(val));
  delay(1000);
  

   

}
void readSensor(){
  int message[1]= {00};
   val = digitalRead(PIRpin);
  if(val==HIGH){
   
    
    if(pirState == LOW){
      message[0] = 00;
      radio.write(message,1);

      pirState = HIGH;
    }
  
  }else if(pirState == HIGH){
    message[0] = 11;
      radio.write(message,1);

      pirState = LOW;
  }
}
