MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541122322 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Dec. 5, 2025, for 'gas leakage detection with auto-off lpg regulator system.'
Inventor(s) include M. Parvathi; S. Kavyasri; M. Devadharshin; K. Harini; and G. Nayandhana.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides an loT-enabled LPG Gas Leakage Detection and Automatic Safety Control System designed to prevent domestic and industrial gas hazards through real-time monitoring and autonomous safety actions. The system uses an LPG gas sensor to detect leakage above 200 ppm, a load cell to measure cylinder weight, a microcontroller for data processing, and a GSM module for SMS alerts without requiring internet connectivity. When leakage is detected, the microcontroller activates an exhaust fan, triggers a buzzer, and closes a solenoid-based regulator shut-offmechanism. Simultaneously, an SMS alert is sent to the user with relevant system information. The system also monitors cylinder weight continuously, sending a "Cylinder Almost Empty" notification when it drups below 2.5 kg. All key parameters-including gas levels, cylinder weight, and safety status-are periodically recorded and communicated to the user via GSM or an loT dashboard. The invention delivers a low-cost, reliable LPG safety solution that integrates leakage detection, cylinder depletion monitoring, automatic shut-off, and re.al-time alerting for enhanced. safety and efficient LPG management."
