Patiala (Punjab), June 1, 2025: Punjabi University is proud to announce the successful registration of a design patent for a cutting-edge Real-Time Air Quality Index (AQI) Detector, developed by PhD scholar Bachandeep Singh Bhathal at the Department of Computer Science and Engineering under the guidance of Dr. Gaurav Gupta and Dr. Brahmaleen Sidhu.
It is worth mentioning that Dr. Gurjit Singh Bhattal and Dr. Priyanka Gupta have also contributed to this research.
Bachandeep Singh Bhattal said that the patented device offers a compact, user-friendly solution for monitoring air quality in closed indoor environments, such as classrooms, hospitals, offices, shopping malls, party halls, theatres and homes.
Dr. Gaurav Gupta said that the benefit of this feature of the device is that by knowing the air quality at any place immediately, efforts can be made to improve it or devise an alternative method.
With indoor air pollution becoming a growing concern in Punjab due to dust, biomass smoke, and inadequate ventilation, this innovation arrives at a critical time.The device has the potential to significantly improve public health outcomes by reducing exposure to harmful air pollutants within indoor settings.
Dr. Brahmleen Sidhu said that unlike conventional AQI systems focused on outdoor monitoring, this device is specifically designed to operate in enclosed spaces.
It continuously tracks and displays real-time air quality metrics, enabling timely interventions such as ventilation or use of purifiers. The design ensures portability, aesthetic integration with indoor spaces, and accessibility for daily use.
Vice Chancellor Dr. Jagdeep Singh congratulated the researcher Bachandeep Singh Bhattal and whole team for this achievement and said that any institution conducting researches that prove to be helpful in making the standard of living for the common people simpler and better testifies to the ability of that institution as well as its priorities.
He said that Punjabi University is proud of the fact that the remarkable work is being done here not only for the promotion of Punjab, Punjabi and Punjabiyat, but also high-level work is being done in the field of science and technology which is even reaching the patent stage.
