Click Video 👇👇👇































👉 Features :

  • Real-time IoT sensor simulation

  • MQTT-based Edge Data publishing

  • Comfort Index computation

  • Interactive GUI with Python


Code :


import time

import random

import json

import threading

import customtkinter as ctk

import paho.mqtt.client as mqtt


# ---------------- MQTT Configuration ----------------

MQTT_BROKER = "broker.hivemq.com"

MQTT_PORT = 1883

MQTT_TOPIC = "fuzzutech/iot/edge"


client = mqtt.Client()

client.connect(MQTT_BROKER, MQTT_PORT, 60)


# ---------------- Sensor Simulation ----------------
