🔥 Flame Guard: Real-Time Fire Detection Using ESP8266 and KiwisIoT Platform

Introduction

Flame Guard is an IoT-based flame detection and monitoring project developed using ESP8266 NodeMCU and a Flame Sensor Module.

The system detects flame conditions and sends sensor data through Wi-Fi to the KiwisIoT Platform for real-time remote monitoring.

🛠️ Hardware Components

• ESP8266 NodeMCU
• Flame Sensor Module
• Jumper Wires
• USB Cable

⚙️ How It Works

1. The flame sensor detects flame conditions.
2. ESP8266 reads the digital output from the sensor.
3. The sensor status is processed by the microcontroller.
4. ESP8266 transmits the data through Wi-Fi.
5. The KiwisIoT Platform dashboard displays the flame status.

🔌 Circuit Connections

📊 KiwisIoT Platform Integration

The project uses two dashboard channels:

• Channel 0: Flame Status (True / False)
• Channel 1: LED Status (1 / 0)

The dashboard provides a simple way to monitor the sensor status remotely.
