Project Title :IoT-Based Smart Smoke Detector

Objective:
To design a smart smoke detection system using IoT that can sense the presence of smoke or fire-related gases and instantly alert users via a mobile app or cloud service, ensuring early fire prevention and safety.

What It Does:

Smoke Detection: Continuously monitors air for smoke or harmful gases (like CO or methane).

Instant Alerts: Sends real-time notifications or SMS/email to users if smoke or gas is detected.

Alarm Activation: Triggers a buzzer or alarm system locally for immediate attention.

Remote Monitoring: Allows users to monitor the status remotely via a mobile app or web dashboard.

Data Logging (Optional): Keeps historical data of gas levels for analysis or safety auditing.

 Key Components:

Smoke/Gas Sensor:

MQ-2, MQ-135, or similar sensors to detect smoke, CO, and other gases.

Microcontroller:

ESP8266 or ESP32 to read sensor data and connect to Wi-Fi.

Alarm System:

A buzzer or siren to alert people nearby when smoke is detected.

Connectivity:

Wi-Fi module (built into ESP32/8266) to send alerts to cloud or mobile apps.

Cloud Platform:

Firebase, Blynk, or ThingSpeak to store and view sensor data remotely.

Mobile/Web Interface:

Displays real-time gas levels and alert status.

Technologies Used:

Languages: C/C++ (Arduino IDE), Python/JavaScript (for dashboard)

IoT Platforms: Blynk, Firebase, ThingSpeak

Sensors: MQ series gas sensors (e.g., MQ-2 for smoke and LPG)

Communication: Wi-Fi (HTTP/MQTT protocols)

Benefits:

Early detection of fire hazards reduces risk of property damage and injury

Remote alerts provide extra safety when users are away

Easy to install and cost-effective compared to traditional systems

Scalable to add more sensors in larger homes or buildings

Applications:

Homes, kitchens, apartments

Schools, offices, and factories

Warehouses or storage areas with flammable materials
