How to send dht sensor's data from arduino to arduino with bluetooth

I want to output the temperature and humidity value to the LCD of Arudino 2 by the hygrometer sensor from Arudino 1.
But I don’t know how to do!
Please teach me how to code this program.

  • Arduino 1

#include <SoftwareSerial.h>
#include “DHT.h”
#define DHTPIN 5
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);
SoftwareSerial bluetooth(3, 2);
float A,B,C;
void setup()
{
Serial.begin(9600);
bluetooth.begin(9600);
dht.begin();
}

void loop()
{
float h = dht.readHumidity();
float t = dht.readTemperature(); //I want to send h,t,f data to Arduino 2.
float f = dht.readTemperature(true);

delay(2000);

}

-Arduino 2
#include <SoftwareSerial.h>
#include <LiquidCrystal_I2C.h>
#include <Wire.h>
SoftwareSerial bluetooth(3, 2);
LiquidCrystal_I2C lcd(0x3F, 16, 2);

void setup()
{
bluetooth.begin(9600);
lcd.init();
lcd.init();
lcd.backlight();
}

void loop()
{
delay(1000);
float h;
float t; // I want to recieve the data ‘h,t,f’ from Arduion 1.
float f;

if (isnan(h) || isnan(t) || isnan(f))
{
lcd.setCursor(0, 0);
lcd.print(“Failed to read”);
lcd.setCursor(0, 1);
lcd.print(“sensor error! “);
return;
}
lcd.setCursor(0, 0);
lcd.print(“Humi:”);
lcd.print(h);
lcd.print(” %”);
lcd.setCursor(0, 1);
lcd.print(“Temp:”);
lcd.print(t);
lcd.print(" C");

}

The process of sending data from one device to another is EXACTLY the same as the process of sending data from the Arduino to the PC. You have the bluetooth device connected to some pins, but you failed to tell us which pins. Use the print() method of the appropriate serial class/instance to send the data. Use available() and read() to read the available data.
