Design and Development of a Low-Cost IoT-Based Smart Kitchen Safety and Automation System

The key contribution of this paper is KitchenGuard, a low-cost smart kitchen system based on ESP32 that goes beyond traditional hazard monitoring by enabling detection, autonomous decision-making and immediate active physical mitigation. In contrast to many existing systems that merely communicate gas detection and alert the users, this paper presented KitchenGuard which features integration of gas-leakage, water-leakage, and motion-sensing with smart automatic gas/water valve isolation, exhaust turn-on/turn-off, alarm notification porting system as well as occupancy-based lighting control in one interoperable architecture.
