```python
from flask import Flask, render_template

app = Flask(__name__)

@app.route("/")
def index():
    return "<h1>Hello, World!</h1>"

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=80, debug=True)
```

Run

```
python3 app.py
```

Open a web browser and navigate to `http://<Raspberry Pi's IP address>` to see the "Hello, World!" page.

### Example 2: IoT Temperature Monitoring using DHT11 Sensor

Use the Raspberry Pi 4 Model B to read temperature and humidity data from a DHT11 sensor and display it on the console.

```
sudo apt-get update
sudo apt-get install python3-rpi.gpio
```

Code

```python
import time
import Adafruit_DHT

DHT_SENSOR = Adafruit_DHT.DHT11
DHT_PIN = 4

while True:
    humidity, temperature = Adafruit_DHT.read(DHT_SENSOR, DHT_PIN)
    if humidity is not None and temperature is not None:
        print("Temperature: {:.1f}C  Humidity: {:.1f}%".format(temperature, humidity))
    else:
        print("Error reading sensor data")
    time.sleep(1)
```

Run

```
python3 dht11_example.py
```

This code will continuously read and display the temperature and humidity data on the console.
