 * @author Eduardo Ventura Chancafe
 * @company SafeHome Smoke Detector Inc.
 * @date 2025
 * @version 1.0
 * 
 * This sketch implements the SafeHome Smoke Detector prototype using ESP32.
 * It utilizes Object-Oriented Programming principles and ModestIoT architecture
 * for embedded applications.
 * 
 * The system monitors gas levels using an MQ-2 sensor and provides visual alerts
 * through LED indicators. Data is transmitted to remote servers via WiFi connectivity.
 * 
 * Hardware Components:
 * - ESP32 DevKit v4 (main controller)
 * - MQ-2 Gas Sensor (smoke/flammable gas detection)
 * - LED with resistor (visual alert indicator)
 * - WiFi connectivity (data transmission)
 * 
 * Key Features:
 * - Real-time gas monitoring with configurable thresholds
 * - Visual alert system with multiple LED patterns
 * - WiFi connectivity with automatic reconnection
 * - JSON-based data transmission to cloud servers
 * - Object-oriented architecture following ModestIoT principles
