MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202621023369 A) filed by Sage University, Indore, Madhya Pradesh, on Feb. 27, for 'apparatus and method for air quality monitoring and purification control.'
Inventor(s) include Ms. Sakshi Agrawal; Dr. Dilip Solanki; Dr. Paras Dubey; Devendra Pawar; Piyush Suryavanshi; Sanjana Singh; and Ishmeet Kaur Kaundal.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "An apparatus (100) for air quality monitoring and purification control comprises a sensor assembly (102) having a particulate matter sensor (104) configured to detect airborne particulate concentrations and generate raw measurement signals, and a non-volatile memory device (106) configured to store calibration coefficients representing factory-determined correction factors specific to the particulate matter sensor (104). An electric motor (110) is configured to generate variable airflow. A hardware processor (108) operatively coupled to the sensor assembly (102) and the electric motor (110) is configured to retrieve the calibration coefficients from the non-volatile memory device (106), obtain the raw measurement signals from the particulate matter sensor (104), apply the calibration coefficients to the raw measurement signals to generate calibrated concentration values, determine a pulse-width modulated duty cycle based on comparison of the calibrated concentration values against predetermined threshold values, and output pulse-width modulated signals for driving the electric motor (110)."
