#include <LoRa.h>
#include <SPI.h>
#include <U8x8lib.h>
#include <DHT.h>// OLED display settings

u8x8.setCursor(0, 0);
u8x8.print("IoT Sensor Node");
// Initialize LoRa module
LoRa.setPins(RX, TX, RST);
LoRa.begin(freq, bandwidth, spreadingFactor, codingRate, preambleLength);
// Initialize DHT sensor
dht.begin();
}void loop() {
// Read temperature and humidity data
float temp = dht.readTemperature();
float humi = dht.readHumidity();
// Display sensor readings on OLED display
u8x8.setCursor(0, 1);
u8x8.print("Temp: ");
u8x8.print(temp);
u8x8.print(" C");
u8x8.setCursor(0, 2);
u8x8.print("Humi: ");
u8x8.print(humi);
u8x8.print(" %");
// Send LoRa packet with sensor data
LoRa.beginPacket();
LoRa.print("T=");
