Code Example: MQTT Publishing with Python

Here’s a simple example of how to publish MQTT messages using Python and the Paho MQTT client library:

import paho.mqtt.client as mqtt
import time

# MQTT broker details
broker_address = "broker.hivemq.com"
broker_port = 1883
topic = "iot/sensor/temperature"

# Create MQTT client
client = mqtt.Client("PythonIoTPublisher")

# Connect to broker
client.connect(broker_address, broker_port)

# Publish messages
for i in range(5):
    message = f"Temperature: {20 + i} C"
    client.publish(topic, message)
    print(f"Published: {message}")
    time.sleep(2)

# Disconnect from broker
client.disconnect()

This script connects to a public MQTT broker, publishes temperature readings to a topic, and then disconnects. It demonstrates the basics of MQTT communication in an IoT context.

Conclusion

The Internet of Things is transforming the way we interact with our environment, from our homes to entire cities and industries. As IoT technologies continue to evolve and mature, we can expect to see even more innovative applications that enhance efficiency, sustainability, and quality of life.
