1. A team of researchers at the Indian Institute of Technology (IIT) Tirupati has developed an android-based mobile app to help the user “see” air pollution levels in their surroundings. 2. The ‘AiR – Pollution Visualiser’ has been developed by the Research in Intelligent Software and Human Analytics (RISHA) Lab, Department of Computer Science and Engineering, IIT-Tirupati in collaboration with Prof Suresh Jain, Department of Civil and Environmental Engineering. 3.
