Development of a Low-Cost Low-Energy Intelligent Reminder System for Unextinguished Gas Stoves

Home automation is a topic of active research in IoT development, and many systems have been proposed for supporting people with their busy lifestyles. To improve the kitchen environment, we previously proposed a smart reminder system for unattended gas stoves during cooking. Here, we describe the further development of this home automation system. The system provides alerts to the user without disruption of cooking because, unlike conventional systems, it does not immediately extinguish the flame when the stove is left unattended. Instead, it monitors for the presence of the user and produces short, periodic alerts. Finally, the system extinguishes the fire if the user does not return to the stove. The system is implemented using several sensors and low-power modules to facilitate cooking while performing other tasks without forgetting that the stove is in use. In this study, we constructed a prototype of the developed system and confirm its applicability through experiments.
