MQTT Smart Sensors Simulation

Introduction

This project simulates a smart sensor system using MQTT protocol for real-time data communication. The system simulates temperature, humidity, and CO2 sensors, publishing their data to specific MQTT topics. It also includes a subscriber that listens to these topics to monitor the sensor data. This is a demonstration of how MQTT can be used for IoT applications, particularly for smart environments.

Installation

Before running the simulation, you need to install the required Python packages. This project relies on the paho-mqtt client. You can install it using pip:

pip install paho-mqtt

Usage

To start the smart sensors simulation, simply run the script from your command line:

python mqtt-comms-demo.py

Features

• Simulates three different types of sensors: temperature, humidity, and CO2.
• Publishes sensor data to specific MQTT topics at one-minute intervals.
• A subscriber listens on the sensor data topics for real-time monitoring.
• Demonstrates MQTT client connections, publishing, and subscribing mechanisms.

Dependencies

• Python 3.7 or newer.
• paho-mqtt package.

Configuration

The main configurations for the MQTT connection and topics are as follows:

• Broker address: test.mosquitto.org
• Port: 1883
• Topics:
  • Temperature: sensor/temperature
  • Humidity: sensor/humidity
  • CO2: sensor/co2

These settings can be modified in the script as needed.
