MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631032111 A) filed by Narula Institute Of Technology, Kolkata, West Bengal, on March 17, for 'iot based aqi detection and air purification model.'
Inventor(s) include Maitrayee Chakrabarty; Kamalika Banerjee; Bansari Deb Majumder; Sudhangshu Sarkar; Antara Ghosh; Souvik Halder; Subham Das; and Saibur Rahaman.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The invention pertains to an IoT-based system for real-time air quality monitoring and autonomous regulation of an air purification apparatus. The system utilizes a multi-sensor array to detect gaseous pollutants and environmental variables, which are processed by a Wi-Fi-enabled microcontroller to determine the Air Quality Index (AQI). Upon the AQI breaching a predefined threshold, the system automatically triggers a relay-controlled air purifier to remediate the indoor atmosphere. The implementation of hysteresis control ensures mechanical efficiency by preventing rapid switching. Furthermore, the system transmits environmental telemetry to a cloud-based dashboard for remote monitoring and historical data analysis. The modular architecture supports the integration of additional sensors and scalability into multi-node networks, providing a cost-effective and energy-efficient solution for indoor environmental management."
