The project requires the 'DHT' library for the DHT11 sensor and the 'LiquidCrystal_I2C' library for the I2C LCD display.

arduino code:

#define DHTPIN 2

#define DHTTYPE DHT11

#define LCD_ADDRESS 0x27 DHT dht(DHTPIN, DHTTYPE);

LiquidCrystal_I2C lcd(LCD_ADDRESS, 16, 2);

void setup() {

Serial.begin(9600);

lcd.init();

lcd.backlight();

dht.begin();

}

void loop() {

float temperature = dht.readTemperature();

float humidity = dht.readHumidity();

lcd.setCursor(0, 0);

lcd.print("Temp: ");

lcd.print(temperature);

lcd.print("C");

lcd.setCursor(0, 1);

lcd.print("Humidity: ");

lcd.print(humidity);

lcd.print("%");

delay(1000);

}
