Indian scientists develop cost effective Photonic system to monitor air quality

With cost-effective monitoring of air quality parameters being critical, a group of scientists has developed an indigenous photonic system for real-time remote monitoring of air quality parameters.

The Gayatri Vidya Parishad Scientific and Industrial Research Centre (GVP-SIRC) and the GVP College of Engineering, Visakhapatnam, scientists are credited with developing the indigenous photonic system titled AUM (Air Unique-quality Monitoring.

The AUM system is an innovative application of the principles of laser backscattering, statistical mechanics, optoelectronics, artificial intelligence, machine/deep learning, and Internet of Things, an official release said. It can identify, classify, and quantify various pollutants simultaneously (of orders of less than one part per billion) and meteorological parameters, with very high precision, sensitivity and accuracy, it said.

AUM was successfully evaluated during laboratory trials with gold standards (in collaboration with EffecTech, UK), and also compared in the field with imported systems from France, and Australia and operated by Karnataka State Pollution Control Board under the aegis of the Central Pollution Control Board of India.

The AUM is portable, compact, low powered and economical, works on plug and play system, requires no setting uptime, and no additional civil infrastructure for housing. It provides information on all gases and meteorological parameters simultaneously. It is a non-intrusive remote, real-time monitoring system with very high sensitivities and accuracies and is capable of monitoring in both spatial and temporal domains, with very high sampling frequencies. Also, the data from spatially separated sensors can be seamlessly streamed to a cloud server, from where digestible real-time encrypted information on dashboard is made available to user at any part of the world, the release said.

This system can boost the nation’s efforts towards self-reliance in high-end technologies and can additionally be instrumental in supporting the endeavours in improving the nation’s health and economy, the release said.
