MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511126788 A) filed by Chandigarh University, Mohali, Punjab, on Dec. 15, 2025, for 'sensor-based autonomous smart fan system without remote control.'
Inventor(s) include Dr. Laxmi Kant Tiwari.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention introduces a sensor-based smart fan system that operates autonomously without the need for a handheld remote control or manual regulator. The system integrates multiple environmental and user-detection sensors, including temperature, humidity, motion, proximity, and an optional light sensor interfaced with a microcontroller-based control unit. The microcontroller processes real-time sensor data to automatically regulate fan speed, mode of operation, and power status based on ambient conditions and user presence. A motor driver circuit executes the control signals to achieve precise speed regulation and energy-efficient operation. A manual override mechanism provides user control in case of sensor malfunction or specific preferences. The invention eliminates remote dependency, reduces energy wastage through presence-based shutoff, enhances user comfort with environment-responsive airflow, and offers a standalone, low-cost alternative to IoT-dependent smart fans. The system is adaptable to ceiling, pedestal, table, and wall-mounted fan designs."
