Relay actuator with button and sensor air humidity?

[arduino_89_89]

relay with button and without gateway, and sensor air and humidity.
How do I insert the temperature sensor skech, within this:

#define MY_DEBUG                               // Enable debug prints to serial monitor

#define MY_RADIO_NRF24                         // Enable and select radio type attached
#define MY_NODE_ID 8


#define MY_TRANSPORT_WAIT_READY_MS 5000        //set how long to wait for transport ready in milliseconds

#include <MySensors.h>
#include <Bounce2.h>

#define RELAY_PIN  4      // Arduino Digital I/O pin number for relay 
#define BUTTON_PIN  3     // Arduino Digital I/O pin number for button 
#define CHILD_ID 1        // Id of the sensor child
#define RELAY_ON 0
#define RELAY_OFF 1

  debouncer.interval(5);
