Development of an Automatic Ventilation System Using Internet of Things for Smart Kitchen Applications

The advancement of the Internet of Things (IoT) has led to significant improvements in the safety and convenience of managing electrical appliances, with remote monitoring and control now accessible to most households. This connectivity allows for a seamless integration of technology into daily life, particularly in environments where safety is a critical concern. This study focuses on the development of an Automated Ventilation System aimed at reducing the risk of kitchen fires and gas leaks. The system uses the MQ-2 gas sensor module, which has been tested with four types of gases: lighter gas, burning paper smoke, steam from boiling water, and Buddha incense smoke, to ensure accurate detection. When smoke levels exceed predefined thresholds, a relay activates the exhaust fan. The system is managed by a NodeMCU equipped with an ESP8266 Wi-Fi module, which enables connection to the Blynk platform. This setup allows users to monitor the system and receive alert notifications on their smartphones, ensuring prompt response when connected to the internet. The implementation of this IoT-based system significantly enhances kitchen safety by providing automated and real-time responses to hazardous smoke levels
