Abstract

The Smart Kitchen Safety Monitoring and Automation System is designed to mitigate the risks of domestic and commercial kitchen accidents, such as LPG leakages and uncontrolled fires. Utilizing the ESP32 microcontroller, the system integrates an MQ gas sensor for leak detection, a flame sensor for fire identification, and a DHT sensor for temperature monitoring. When hazardous levels are detected, the system triggers an immediate local alarm via a buzzer and executes safety protocols through a relay module, such as activating an exhaust fan or shutting off a valve. Simultaneously, the system leverages Wi-Fi/GSM connectivity to send real-time notifications to the user's smartphone. This proactive approach ensures rapid response times, reducing the likelihood of catastrophic property damage and ensuring human safety through automated environmental surveillance.

Project Description

Kitchens are high-risk environments where gas leaks and unattended cooking can lead to devastating fires. Traditional smoke detectors often trigger too late, after a fire has already started. The objective of this project is to develop a comprehensive monitoring system that identifies threats at the incipient stage. The system focuses on three primary vectors: combustible gas concentration, the presence of open flames, and abnormal ambient temperature spikes. By employing a multi-sensor fusion approach, the ESP32 processes analog and digital signals to determine the severity of the hazard. If a gas leak is detected, the system is programmed to activate an exhaust fan via a relay to disperse the gas and alert the user. If a flame is detected, the system triggers a high-decibel buzzer and sends an emergency notification via the internet. The integration of IoT allows users to monitor their kitchen status remotely, providing peace of mind and a critical layer of security for elderly users or commercial restaurant operators. This project bridges the gap between simple alarms and fully automated safety systems, emphasizing reliability, low latency, and ease of installation to provide a scalable solution for modern urban housing.
