Overview:

The Smart Fire Safety System is an IoT-based fire detection and response solution designed to monitor indoor or outdoor environments in real-time and immediately detect signs of fire such as smoke, gas leaks, and temperature rise. Once a threat is detected, it automatically triggers alarms, notifies concerned personnel via SMS, email, or app notifications, and can even activate automatic fire suppression systems like water sprinklers. This system significantly reduces emergency response time and helps prevent disasters.

Key Features:

• Multi-Sensor Detection:
  Uses a combination of temperature sensors, smoke detectors, and gas sensors (e.g., MQ-2) to detect fire or hazardous conditions.

• Real-Time Alerts:
  Sends instant alerts to registered users and fire departments via SMS, mobile app notifications, or email.

• Automatic Sprinkler Activation (Optional):
  If fire is detected, it triggers a connected relay to activate water sprinklers.

• Location Tracking:
  Pinpoints exact location of fire on a map-based dashboard, especially useful for large buildings or campuses.

• Web Dashboard:
  Admin panel to monitor all sensors, status logs, and receive notifications.

• Battery Backup & Offline Alerting:
  System remains operational during power failure and can use buzzer/alarm as a local alert mechanism.

Technology Stack:

• IoT Hardware:

  • Sensors: Flame Sensor, Temperature Sensor (LM35 or DHT11), Smoke Sensor (MQ-2), Gas Sensor

  • Microcontroller: Arduino Uno / ESP8266 / ESP32

  • Connectivity: Wi-Fi Module (ESP8266) or GSM Module for SMS

• Backend:

  • PHP / Java / Node.js (handles data storage, alert rules, logs)

  • RESTful APIs to receive sensor data from IoT devices

• Frontend (Web/App UI):

  • HTML, CSS, Bootstrap, JavaScript

  • Optional: Progressive Web App (PWA) or Android app (Java/Kotlin)

• Database:

  • MySQL / Firebase / MongoDB for storing sensor logs, user profiles, and alert history
