# 🛠️ Safe Kitchen: Smart Kitchen Alarm System (IoT-Based)
## 📘 Overview
**Safe Kitchen** is an IoT-based project designed to prevent gas leaks and fires in household kitchens. It integrates gas, flame, and temperature sensors with real-time monitoring via Node-RED and Ubidots, alerts through SMS using Vonage, and local data storage on a Raspberry Pi.
---
## 🔥 Why This Project?
Kitchen-related incidents remain a major cause of house fires and fatalities worldwide. Many of these are preventable with early detection systems. Common causes include:
- Leaving food unattended on stoves.
- Forgetting burners or ovens on.
- Using loose clothing near heat sources.
- Placing flammable objects near heat.
Despite warnings, accidents continue to rise. This project aims to build a smart, user-friendly, and low-cost system that detects early warning signs and alerts residents and emergency services promptly.
---
## 🎯 Project Objectives
### General Objective:
Develop a smart alarm system to prevent kitchen accidents caused by gas leaks and fire hazards.
### Specific Objectives:
- 🔍 Detect environmental changes in the kitchen using gas, flame, and temperature sensors.
- 📊 Display sensor data via a local dashboard and cloud platform (Node-RED and Ubidots).
- 🚨 Trigger alarms and send SMS notifications in case of gas or fire detection.
- ☁️ Enable cloud connectivity and mobile access for users.
- 💡 Maintain a low-cost and user-friendly design.
---
## 🧩 System Architecture
The system consists of the following components:
- **ESP32** microcontroller for sensor data acquisition.
- **Raspberry Pi** for data processing and dashboard control via Node-RED.
- **Sensors:** gas, flame, temperature.
- **Cloud integration** using MQTT and **Ubidots**.
- **Local storage** using SQLite and CSV export.
- **SMS alerts** via Vonage API.

### 🧠 Conclusions
The proposed system was successfully designed and built with a web socket interface and Wi-Fi communication.
Sensor integration and MQTT communication were validated.
The system shows promise for low-cost domestic safety solutions.
Future improvements may include:
- Direct ESP32-to-Ubidots MQTT integration.
- Evaluation of alternative microcontrollers and protocols.
- Testing additional sensors for accuracy and cost-efficiency.
