Abstract: The present invention relates to an embedded safety control system for domestic gas stoves, designed to prevent accidental gas leakage at the source through intelligent verification of user intent and real-time flame correlation. Gas leakage in household kitchens is a significant safety concern, often leading to fire hazards and explosions. Conventional systems primarily act as postdetection alarm mechanisms and fail to prevent gas discharge during ignition failure. The proposed system introduces a fail- safe smart gas stove knob integrated with an embedded control unit that ensures gas flow only under verified safe operating conditions. The system incorporates a rotary encoder to detect intentional user interaction through knob rotation, thereby confirming usage intent. Upon activation, the system initiates a time-bound verification process wherein the presence of flame must be detected within a predefined time window of approximately 3 to 5 seconds using a flame sensor. Simultaneously, a gas sensor continuously monitors ambient gas concentration levels. In scenarios where gas flow is initiated but flame detection fails within the specified time window, or abnormal gas concentration is detected, the system triggers an automatic corrective response. A servo motor mechanism reverses the knob position to shut off gas flow immediately, thereby preventing hazardous gas accumulation. Additionally, an alert system comprising a buzzer and visual indicators is activated to notify the user. The system is powered by an ESP32 microcontroller and operates based on a state-driven safety algorithm that ensures reliable, real-time decision-making and fail-safe operation. This invention emphasizes preventive safety through the integration of usage-intent verification and time-bound flame correlation, offering a proactive solution to mitigate gas-related domestic hazards. This innovation is novel in its approach to combining user intent validation with dynamic flame monitoring and automated gas shut-off, making it highly suitable for provisional patent filing.
