Scientists at Gayatri Vidya Parishad-Scientific and Industrial Research Centre in Visakhapatnam have developed an indigenous system for real-time remote monitoring of air quality parameters, the Department of Science and Technology (DST) said. The Air Unique-quality Monitoring (AUM) system is an innovative application of the principles of laser backscattering, statistical mechanics, optoelectronics, artificial intelligence, machine/deep learning, and Internet of Things.
  1. 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.
  2. The AUM system was successfully evaluated during laboratory trials. It was also compared in the field with imported systems from France and Australia, and operated by the Karnataka State Pollution Control Board under the aegis of the Central Pollution Control Board of India.
  3. The system had CATS Eco-Systems, Nashik as the technology transfer partner for commercialisation.
  4. It has been found to be highly sensitive and accurate and capable of simultaneous detection and quantification of all air quality parameters and offers a number of merits over any of the currently available conventional systems.
  5. It is portable, compact, low powered and economical, works on plug and play systems, requires no setting up time, and no additional civil infrastructure for housing.
  6. The system also provides information on all gases and meteorological parameters simultaneously.
  7. 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.
  8. Also, the data from spatially separated sensors can be seamlessly streamed to a cloud server, from where digestible real-time encrypted information on the dashboard is made available to users at any part of the world
