MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051256 A) filed by Nitte Meenakshi Institute Of Technology, Nitte; Abhayy Venkatesh; Chirag M Yadav; C Bhanu Varun; and Dr Kiran Aithal S, Bangalore, Karnataka, on April 22, for 'guards: gas usage analytics and risk detection system.'
Inventor(s) include Nitte Meenakshi Institute Technology, Nitte; Abhayy Venkatesh; Chirag M Yadav; C Bhanu Varun; and Dr Kiran Aithal S.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an Internet-of-Things (IoT) enabled, retrofit-compatible smart safety and consumption monitoring system for domestic liquefied petroleum gas (LPG) stoves, designated as the Gas Usage Analytics and Risk Detection System (GUARDS). The system comprises a microcontroller (106), preferably an ESP32, coupled to a gas leak sensor (101), at least one load cell (102) arranged beneath a burner (304) through a signal conditioning amplifier, a knob position potentiometer (103) mechanically coupled to the rotary knob (307) of the stove, a servo-operated shut-off valve (110), a buzzer (108), a light-emitting diode indicator (109), a Wi-Fi communication module (111) and a cloud server with an associated mobile application (112). The microcontroller continuously samples the sensors, evaluates multi-condition safety thresholds and, upon detection of an unsafe condition such as airborne LPG leakage or operation of the burner without a utensil within a fifteen-second window of knob activation, closes the servo-operated shut-off valve and issues both local audio-visual alerts and remote push notifications. Simultaneously, the microcontroller estimates per-session LPG consumption using experimentally calibrated flame-level-dependent flow rates, maintains a running cylinder-mass estimate, generates hierarchical low-gas warnings at approximately 25 percent, 10 percent and 5 percent remaining, and categorises usage into morning, afternoon, evening and night time-of-day bands for analytics on the mobile application. The present invention ensures enhanced kitchen safety, optimised LPG consumption, predictive refill alerting and non-invasive retrofit installation on conventional LPG stoves without any modification of the gas supply pipeline."
